It has long been known that melanomas contain the melanin pigment. The presence of the pigment in the melanotic tumor is due to the action of oxidases which catalyze the oxidation of tyrosine to melanin. Evans et al. reported that the biosynthesis of melanin from tyrosine may very probably pass through the precusors,5,6-dihydroxy-2,3-dihydro-indole-2-carboxylic acid (Ⅰ) and then 5, 6-dihydroxy-indole (Ⅱ) as shown by the scheme in the Chinese text.Compound (Ⅱ) had been synthesized by Beer.

It has long been known that melanomas contain the melanin pigment. The presence of the pigment in the melanotic tumor is due to the action of oxidases which catalyze the oxidation of tyrosine to melanin. Evans et al. reported that the biosynthesis of melanin from tyrosine may very probably pass through the precusors,5,6-dihydroxy-2,3-dihydro-indole-2-carboxylic acid (Ⅰ) and then 5, 6-dihydroxy-indole (Ⅱ) as shown by the scheme in the Chinese text.Compound (Ⅱ) had been synthesized by Beer. According to its properties, this compound was believed to be the actual precusor of melania.This conclusion was supported by the biochemical work of Mason.It is also interesting to note, that the essential constituents of one of the anticancer Chinese drug, "Fan-mu-pieh" (番木鳖), are indole alka oids. Therefore, the preparation of indole com-pounds, especially [bis-(β-chloroethyl)-amino]-indole derivatives, would be a hopeful new route for the synthesis of effective drugs in the treatment of cancer especially melanomas.In the present investigation, 5-[bis-(β-chloroethyl)-amino]-indole-2-carboxylic acid (Ⅵa), 6-[bis-(β-chloroethyl)-amino]-indole-2-carboxylic acid (Ⅵb) and 7-[bis-(β-chloroethyl)-amino]-indole-2-carboxylic acid (Ⅵc), structurally related to the precusor Ⅰ of melanin were prepared. If these compounds should be decarboxylated in vivo, they would be converted to bis-(β-chloroethyl) amino-indoles, structually related to the other precusor Ⅱ of melanin.Compound Ⅵb was prepared by a 7-step synthesis from 2,4-dinitrobenzaldehyde (Ⅶ). The latter was converted to 2-methyl-4-(2'4'-dinitrobenzylidene)-5-azIactone (Ⅷ) and the azlactone was hydrolyzed to 2,4-dinitrophenyl pyruvic acid (Ⅸ), and subsequently transferred to its ethyl-ester (Ⅹ) by the usual way. 6-[Bis-(β-hydroxyethyl)-amino]-indole-2-carboxylic acid (XIV) was obtained either by reducing Ⅹ with sodium hydrosulphite or by hydrogenating it catalytically on palladium-carbon to the amino compound (XIII), and followed by dihydroxyethylation in dilute acetic acid with ethylene oxide. Compound XIV was chlorinated with phosphrous oxychloride and the chlorinated compound (XV) was hydrolyzed to final product Ⅵb with hydrochloric acid.Compounds Ⅵa and Ⅵc were prepared from the ethyl esters of the corresponding nitroindole-2-carboxylic acids (Ⅶa and Ⅶc) through reduction, hydroxyethylation, chlorination and hydrolysis as in the preparation of Ⅵb. The intermediates Ⅻa and Ⅻc were obtained from p-nitrophenyl-hydrazone and o-nitrophenylhydrazone of ethyl pyruvate Ⅺa and Ⅺb respectively by modified Parnerter's method. Besides, some derivatives of indole-2-carboxylic acid such as N,N-bis-(2-chloroethyl)-indole-2-carboxylic acid amide (XVI), indolyl ethyleneimine (XVII) and 3-iodo-indole-2-carboxylic acid (XVIII) were also prepared.Compounds Ⅵa and Ⅵc showed inhibiting action against sarcoma 180 and melanoma in mice, but compound XVI, XVII and XVIII have no effect toward sarcoma 180. The pharmacological actions of the above compounds will be reported elsewhere.

The discovery of the larval form of the species of Asymphylodora Looss (1899) dated back to the time of von Baer (1827), who described Cercaria paludinae impurae, De Filippi (1854) recorded from the same snail host a distome bearing the same name. For one and half century knowledges regarding the developmental life history of the well-known type of the genus, A. tincae, have gradually accumulated. Small as it is, the worm, however, has received the attention of many a distinguished helminthologists such as Diesing (1858), Looss (1899). Lithe (1809), Fuhrmann (1916), Dubois (1909), Wesenberg-Lund (1934) and Skrjabin (1955). The recent work of Deblock, Capron and Biguet (1957) elucidated the life cycle of a new subspecies, A. tincae var. mediagraba, while other workers like Serkova and Bykhovskii (1940), Biguet, Deblock and Capron (1956) and Stunkard (1959) described the development of several progenetic species, The significance of progenesis to the phylogeny of Digenea is discussed by Stunkard (1959). Inspire of the above-mentioned important advances on the knowledge of this genus, there still remain much to be worked out regarding the biology of this group.The present communication repoorts life history studies on Asymphylodora macostoma Ozaki, 1925 and A. japonica Yamaguti, 1928.The adults of A. macrostoma were obtained from Puntia sp. (Cyprinidae) occurring in the mountain stream of Yungan, Central Fukien. Their structure and measurements were described in detail. They are indistinguishable from the original description of Czaki (1925) and Yamaguti (1938). The molluscan intermediate host of A. macrostoma in Fukien is Melania peregrinorum Heude inhabiting the mountain stream among rocks and under stones.The sporocyst stage was not discovered in natural infection. The second generation redia measures 1.39mm in length and 0.274mm in width. The gut contains numerous brownish granules derived from the host tissue. The general shape of the redia is sac-like. It possesses no muscular feet. In the body of a mature redia there are 5 or 6 cercariae and some germ-balls observed.The cercariaeum is a comparatively large distomate larva 0.3-0.37mm in length and 0.11-0.13mm in width. It is brownish yellow ia color especially in its posterior part. The cuticle is covered with spines distributed in transverse rows. The oral sucker measures 0.08-0.09mm by 0.09-0.097mm in diameter. The ventral sucker is smaller, measurihg 0.068 in diameter. On the dorsal wall of the oral sucker there are four rows of short conspicuous spines lining two-thirds of the inner surface of the sucker. There are also 3-8 big flat spines attached to the inner surface. The acetabulum is also armed with small conspicuous spines on its entire inner surface, Such spinulation is not present in the cercariaeum of A. japonica but is rather similar to that described in Cercariaeum squamosum by Deblock, Carpron and Biguet (1957). The oral sucker is followed by a short prepharynx, which leads to a globular pharynx. The esophagus is long, bending several times and bifurcating in front the acetabulum into two intestinal caeca. On both sides of the esophagus four bundles of penetration glands are present, occupying the area between the pharynx and acetabulum. There are altogether 40-42 unicellular gland cells. Four bundles of ducts proceed anteriorward along the medial and lateral regions to arrive at and open on the inner dorsal wall of the oral sucker. The penetration glands become graduallv diminished as the cercariaeum grows more mature, so that in the adolescaria stage their contents are greatly reduced. The posterior tip of the body is armed with a number of long and sharp spines, which probably help the larva in its creeping movement.The excretory system is complicated. Since the body of the cercariaeum is full of cystogenous cells, which obscure the capillary tubules connecting the flame cells, their arrangement cannot be traced, and yet when the cercariaeum has encysted, while still in the snail host, most of the gland cells have disappeared rendering the tiny excretory tubules observable. The excretory bladder is a sinuous tube, making one or two left and right bendings as it advances anteriorward. The bladder is lined with a series of large epithelial cells. From the anterior aspect of the bladder, there arise two collecting tubules, which extend obliquely foreward to both lateral fields. They continue to advance to the level of esophagus and then turn posteriorly to about the mid region of the whole length of the collecting tubule and divides into two branches. The anterior branch gives off branches two times resulting in three groups of solenocytes. The first group consists of five cells, while the other two have three calls cach. The posterior branch divides into two main sub-branches with seven and three flame cells in each group. The total number of flame cells is about 42. The pattern of their arrangement can be better understood by tracing the development of the excretory system from the germ-ball to the mature cercaria. Four stages were observed:1. In the early germ-ball stage, when the oral sucker and the phraynx are being differentiated, the collecting tubulesare formed. They are connected to a small bladder situated at the posterior end of the body. The two tubules having passcd anteriorly and reached about two-thirds of the body length, make a characteristic loop and divide into an anterior and a posterior branch Their arrangement can be depicted as 2(1+1)=4. 2. In the second stage, when the ventral sucker is formed, both the anterior and posterior branches divide into three flame cells cach. The formula is reprsented as 2(3+3)=12.3. In the third stage the division of the anterior branch into three smaller branches is witnessed. The posterior branch is not subdivided. It still possesses three solenocytes. The formula of arrangement is 2[(2+2+4)+(2+1)]=22.4. The fourth or the cercaria stage shows great increase of cells, especially in the posterior branch. Their arrangement are indicated in the foregoing description. The formula can be expressed as follows: 2[(3+3+5)+(3+3+4)]=42.It was observed that the number of cells and the pattern of their arrangement are not exactly homologous between the left and right sides of the body. The above description indicates that the cell formula is constant only in relative sense that is they differ in different stages of development.Specimens of Asymphylodora japonica were secured from Pscudorasbora parva (Temm. aud Schle.) and also from Cyprinus carpio L. The structure and measurements of the adult are fully described. They resemble the original description of Yamaguti's closely. A. japonica develops in Parafossarulus eximius (Frauenfeld) and P. striatulus (Benson). Both molluscs inhabit the ponds and rivulets in Foochow area. Dissections of the snails reveal stages of rediae and cercariae. Spororcysts were not found in the natural infection. The second generation redia is elongated in shapeIt measures 1.5mm in length and 0.45mm in transverse diameter. The fully mature redia contains seven to eight cercariae in its body.The cercariaeum is elongated or spindle-shaped, measuring 0.5-056mm in length and 0.16mm in greatest width. The cuticle is armed with spines transversely arranged. Oral sucker is round in shape with a diameter of 0.1mm. Ventral sucker, larger than the oral sucker, has a diameter of 0.12-0.13mm. There is a short prepharynx followed by a glubose pharynx. The esophagus is long. It bifurcates in front of the acetabulum into two intestinal caeca, which extend posteriorly to one fourth of the body length from the hind extremity. Four groups of unicellular penetration glands occupy the region between the oral and ventral suckers, numbering altogether about 36-38. Four bundles of gland-ducts lead forward and open on the inner dorsal wall of the oral sucker. The excretory system resembles that of cercariaeum of A. macrostoma. The excretory bladder is a long sinuous tube, similar to that of cercariaeum A. macrostoma.The metacercariae of A. japonica, probably in the pre-encystment stage, were frequently encountered in the snail host. It is larger in size than the cercariaeum, measuring 0.8-1.00mm in length and 0.4mm in greatest width, Oral sucker 0.038-0.11mm in diameter, is smaller than acetabulum, The later is 0.132-0.149 mm in diamcter. The oral sucker is smaller than acetabulum. The later is 0.132-0.149 mm in diam- eter. The oral sucker is followed by a prepharynx, which is connected to a glubose pharynx 0.049-0.50mm in diameter. The esophagus is long It bifurcates before the ventral sucker into two intestinal caeca extending to the hind end of the testis. The genital organs alrsady begin to develop. A single oval testis, measuring 0.30 by 0.20mm is situated at the posterior part of the body. Immediately anterior to the testis, an ovary triangular or oval in shape is present. Its diameter is 0.10mm. On the right side of the acetabulum the primordium of the cirrus pouch and metraterm appear as two columns of nuclei. The metacercariae can encyst in the same snail host. They can also migrate to another snail of the same species. The cyst measures 0.332-0.365mm in diameter. Under cover-glass pressure, it measures 0.500mm in diameter.Experiments were performed to infect Puntia sp., secured from places where no Melanin snails were found, and members of which were found to be free from infection, by feeding them with from Melanin peregrinorum. Fifteen days after infection, the fishes were dissected and adult worms similar to A. macrostoma were found. One experimentally infected fish died five days after infection wite forth immaure worms found. They were all very similar in size and development. Experiments were also performed to secure adult A. japonica by feeding laboratory-reared gold fishes (Carassius auratus) with cysts from Parafossarulus exiraius (F.) Fifteen days after infection, ad

From 32 rhesus monkeys the vermis cerebelli and the portion containing the dentate nucleus were fixed in 10% formalin.The animals of both sexes were divided into 4 age groups according to their dental status.Paraffin sections as well as frozen sections were prepared.The Purkinje cells per unit area of the cortex were estimated on sec- tions stained with methyl green and pyronin.With advancing of age the numbers of the Purkinje cells decreased gradually,with an average reduction from 1391 to 1065 in the males and from 1203 to 1108 in the females.Histochemically the lipofuscin pigments differed from melanin and hemosiderin.They were almost insoluble in fat solvents,readily stained by Sudan black B,and were PAS-positive.The pigments in group Ⅳ usually appeared acidfast with the long Ziehl-Neelsen method,while those in the younger age groups were stained poorly or not at all.With Schmorl's ferricyanide method,only the pigments in the Purkinje cells of group Ⅳ reacted positively.Theese characteristics indicated that the pigments belonged to the ceroid-type lipofuscin as des- cribed by Pearse (1960).The magnitude of the pigments in both types of cells was es- timated in the Sudan black B-stained sections.In both sexes the numbers of pigmented cells and the cells with higher grades of pigmentation were found to be increased con- comitantly with the increase of age.The difference were statistically significant.The pigments of Purkinje cells were more or less uniform in size and accumulated lateral to or above the nuclei.The pigments in the neurons of dentate nucleus varied in size and distribution in the cytoplasm.In both types of the cells pigments were found occasion- ally in the dendrites.
