In 1928 Curt demonstrated that non-human schistosome cercariae are capable of producing dermatitis in man. Since then many species of avian and mammalian schistosomes have been shown to produce similar disease in different parts of the world. In 1958 a kind of schistosome dermatitis locally known as 'Ya-Mu-Lan' (meaning duck-saliva-disease) was discovered in Foochow, Fukien Province. The infection occurred among farmers who waded in canals and ditches, while taking care of ducks in their natural environment. The same dermatitis was reported from Yung-siao district bordering Kwangtung. In Szechwan a similar disease was reported by T. C. Pap (1957) where it was known as 'Ya-Si-Feng' (meaning duck-feces-disease). From the endemic area in Foochow, 10, 145 snails belong to the species Lymnaea (Radix) plicatula Benson were examined and a kind of ocellated fork-tailed cercaria was discovered. Another closely related snail, Lymnaea (Fossaria) ollula Gould was also found infected but the incidence of infection was somewhat lower. Experiments were conducted to infect laboratory reared ducklings and full grown ducks, the feces of which were examined to be free from schistosome eggs. Ten to twelve days later edult worms were recovered in the mesenteric and portal veins and a few specimens were found in the lungs and heart. Lymnaea (Radix) plicatula were also experimentally infected with miracidia hatching out from eggs secured from the infected duck.Studies on the morphology of both the adult worms and the developmental larval stages were made and the details are reported in the present communication.Our observation indicates that the worm belongs to a species of Trichobilharzia different from any other known species. The name Trichobilharzia paoi sp. nov. is proposed after Prof. T. C. Pap of Chungking Medical College, Szechwan.Description of the adult worm:Male: Body slender, total length 5.35-7.31mm. width 0.076-0.095mm. Oral sucker measures 0.051-0.060ram×0.043-0.060mm in diameter. Ventral sucker, the surface of which is armed with small spines, measures 0.051-0.060mm in diameter. Oesophagus. bifurcates anterior to the ventral sucker at a distance about anterior two-thirds between oral sucker and acetabulum. Intestinal caeca iun posteriorly on two sides and reunite behind the gynaecophoric canal, which is a longitudinal slit 0.237-0.380mm in length and 0.123-0.152mm in width. Gynaecophoric canal is foimed by inward folding of two lateral sides of the body bearing numerous spines. Testes round, 70-90 in number arranged in a single longitudinal row. Their diameter ranges 0.051-0.064mm. Seminal vesicle occupies an area from a level immediately posterior to the ventral sucker to the fore margin of gyneacophoric canal. It measures 0.172-0.447mm in length and 0.038-0.055mm in width.Female: More delicate than male, length 3.38-4.89mm, greatest width 0.076-0.114mm. Oral sucker terminal with mouth openning on its ventral aspect, diameter 0.051-0.056mm×0.038-0.051mm. Ventral sucker, a small solid organ, measures 0.030-0.040mm×0.035-0.043mm in diameter. Oesophagus bifurcates at some distance before the acetabulum. Intestinal ceaca reunite behind the ovary, forming a single caecum passing to near the posterior end of body. Ovary spiral in shape with a length 0.253-0.352mm and a width 0.021-0.025mm. Seminal receptacle elongated in form, is connected to the ovary on its posterior aspect. A Laurer's canal is present. It originates from Seminal receptacle and opens to the exterior. The oviduct starts from the ovary, runs parallel with the vitalline duct to the anterior of ovary, where they unite together forming the ootype, surrounded on all sides by a cluster of unicellular Mehlis glands. The uterus is short and contains only one egg. Female genital pore is immediately postacetabular. Egg is spindle or elongate oval in shape with a sharp curved spine at one end. Egg measures 0.236-0.316mm×0.068-0.112mm. Avian schistosomes parasitising domestic and wild ducks and other birds belong to the subfamily Bilharziellinae Price, 1929, and family Schistosomatidae Looss, 1899. They were formerly considered to belong to two genera, namely Pseudobilharxiella Eismont, 1929 and Trichobilharzia Skrjabin and Zkharow, 1920. Yamaguti (1958) consideted Pseudobilharziella to be the synonym of Trichobilharzia and listed 22 species in his "Systema helminthum". Recent additions of some new species made up the total of about 25 species. In comparing the structure, it is found that the Chinese species belongs to those duck schistosomes with spindle-shaped eggs. Among them the most closely related is T. yokogawai (Oiso, 1927), from which it differs in several important aspects, such as the size of the worm, the extent of gynaecophoric canal, number of testes and size of eggs. Their different characters are tabulated as follows:T. yokogawai T. paoi n. sp. Male Body length 2.0-2.75mm 5.35-7.31mm (Foochow specimen)average 2.336mm 4.0-10.3mm (Chungking specimen) Position of immediately behind 0.371-0.495mm behind gynaecophoric Acetabulum acetabulum (Foochow specimen) canal 0.35-0.57mm behindacetabulum (Chungking specimen) T. yokogawai T. paoi n. spLength of 0.2mm 0.247-038mm (Foochow specimen)gynaecophoric 0.35-0.41mm (Chungking specimen)canalNumber of 50-70 70-90 (Foochow specimen)testes 50-85 (Chungking specimen)Size of eggs Length 0.204-0.238mm 0.236-0.316mmWidth 0.051-0.068mm 0.068-0.112mm (Foochow specimen)0.215mm0.075mm (Chungking specimen)From the above table it can be noticed that these two species can be distinguished by these essential differences.T. paoi is, furthermore, differentiated from T. physellae, another closely related species by the number of testes, which is about 210-240 in the latter and are arranged in two to three rows. Tanaka (1960) reported another duck schistosome from Oki Island, which he identified as T. physellae. According to this auther, the male has only 52-78 testes, the seminal vesicle is much shorter reaching only about half distance between gyaaecophoric canal and the acetabulum. Another striking difference is that the intestinal ceaca of T. physellae from Oki Island reunite at the region anterior to the seminal vesicle, while in T. paoi they reunite behind the Seminal receptacle at the level anterior to the gynaecophoric canal.Macfarlane (1944, 1949) and Olivier (1949) have shown that the dermatitis produced by avian schistosomes is a sensitization phenomenon. They have demonstrated striking differences in the reaction of skin of infected animals to the penetration of cercariae in the initial and subsequent infections, and presented evidence for the ideathat human cases also become increasingly allergic to the protein of invading schistosome cercariae. In order to make further inquiries on this problem and to investigate whether Chinese species of Trichobilharzia will induce similar reactions in the mammalean host, experiments were conducted to infect laboratory-reared white mice and biopsies made of the skin in the first and also after a series of repeated infections It is with the purpese to observe the behavior of the cercariae after having penetrated into the body of an abnormal host, and to trace the course of their migration and destiny.1. Tissue reaction in primary infection: Histological sections were made on biopsies on various intervals after infection, one and half hour, 3 hours, 5 hours, 8 hours, 21 hours etc. At one and half to three hours after exposure, the cercariae already penetrated the epidermis. Some of them were in the hair follicles. A few arrived at the corium. Those just penetrated Corneum stratum were found lying there horizontally, and usually there was a small tunnel or cavity, formed among the epithelial cells, surrounding each cercaria. Such phenomenon is similar to that as observed by Gordon and Griffiths (1951) on the behavior of the cercaria of Schistosoma mansoni. Olivier and Weinstein (1953) also observed the same in Trichobilharzia ocellata. During early hours of invasion there was apparently very little cellular response to the cercariae. Those, which invaded the corium, were surrounded by a small number of leucocytes. Apparently the cercariae were still in good condition. They were probably living at the time of biopsy as indicated by their intact cell structure being well stained, 21 hours after infection, the tissue shows more infiltration of white cells and histiocytes. More of them gathered around the cercariae, some of which appeared as having signs of histolysis, while others seem still quite normal. Observations made on tissues fixed at later hours after infection indicated that even in the primary exposure, great majority of the invading cercariae were already arrested and immobilized in the epidermis and not able to invade further into the body.A small part of the cercariae, however, were found to migrate to the lung tissue. They were evidently being carried by the blood stream to the new site, where they produced considerable tissue damage and hemmorrhage. In our experiments with mice infected 20 hours previously, petechial hemorrhages were present on the surface of the lung. Infection experiments were conducted on 19 mice, each of which was infected with 80 to 250 cercariae. Dissections of the animals were made at various intervals from one day to about a month since exposure. The largest number of worms and hemorrhagic spots were found on the lung tissue during the second and third day after infection. Of the 19 mice, 15 were found to show pulmonary lesions. The number for each mouse ranges from one to 86. From eleven of them, worms were recovered from the tissue and from each mouse from one to 15 worms were counted. When the dissections were made during the first three days, the worms were still living. As time elasped, only formation of nodules were found. Sectioned nodules contained worms which were either dead or moribund.2. Tissue reaction in repeated infecti

The manner of branching of the proper hepatic artery,its relationship with sur- rounding structures and the source of origin of the left,right and middle hepatic ar- teries were examined in 50 Chinese child cadavers. The proper hepatic artery was found in 45 cases with 5 cases devoid of this artery. In the 45 cases the proper hepatic artery divided itself into a left and a right hepatic artery in 37 cases (74%);a right and a middle hepatic artery in 2 cases (4%) and in 1 case each (2% each) into a left and a middle or a left,a right and in addition a middle hepatic artery.In the remaining 4 cases the proper hepatic artery was either continued into the middle (1 case,2%) or the right (1 case,2%) or the left (2 cases, 4%) hepatic artery. The proper hepatic artery was situated on the left side of the portal vein in 17 cases (34%);left and anterior to this vein 16 cases (32%) and in front of it in 8 cases (16%).The point of division of the proper hepatic artery was on the left side of the common bile duct in 32 cases (64%). In the 50 cadavers there were 52 right hepatic arteries,2 of which being the acces- sory right hepatic arteries derived from the left hepatic or the gastroduodenal artery.In the remaining 50 cases,those derived from the proper hepatic artery comprised the most of the cases (39 cases,78%),others were from the common hepatic artery (4 cases,8%) or the superior mesenteric artery (3 cases,6%).There were 7 cases in which the artery was derived from the superior mesenteric artery (3 cases,6%). The number of the left hepatic artery was 57,of which 7 being the accessory type, derived from the left gastric (4 cases,8%) or the right hepatic (3 cases,6%).The origin of 50 left hepatic arteries was mainly from the proper hepatic artery (38 cases, 76%) or the common hepatic artery (5 cases,10%).The remaining 7 cases were derived from the left gastric artery (5 cases,10%). The middle hepatic artery was found in 341 cases (82%) derived either from the left hepatic (24 cases,48%) or the right hepatic artery (13 cases,26%).Only few arose from other sources. The branching of the proper hepatic artery was classified into 9 types;the first type comprised the majority of the cases (30 cases,60%),in which the left and right hepatic arteries were derived from the proper hepatic or common hepatic artery with the middle hepatic artery derived from the left,right or the proper hepatic artery.

Acute experiments were performed on rabbits anesthetized with urethane. The change of concentration of plasma free fatty acid (FFA) was observed after electrical stimulation of the peripheral ends of left greater splanchnic nerves. The results were as follows: (1) In normal rabbits with intact adrenal glands, the effect of stimulation of splanchnie nerves upon the plasma FFA level was rather inconsistent, the result being either an increase, or a decrease, or no change. (2) After left adrenalectomy, however,...

Acute experiments were performed on rabbits anesthetized with urethane. The change of concentration of plasma free fatty acid (FFA) was observed after electrical stimulation of the peripheral ends of left greater splanchnic nerves. The results were as follows: (1) In normal rabbits with intact adrenal glands, the effect of stimulation of splanchnie nerves upon the plasma FFA level was rather inconsistent, the result being either an increase, or a decrease, or no change. (2) After left adrenalectomy, however, a marked decrease in the plasma FFA level was obtained after splanchnic stimulation in all the rabbits observed. The effect was abolished When the α-cells of the pancreatic islets were selectively destroyed by the administration of cobalt chloride. This effect was repeated in acute experiments performed on dogs with blockade of left adrenal venous return. A marked decrease in the plasma FFA with concomitant hyperglycemia was observed after splanchnic stimulation. This effect was abolished after extirpation of the body and tail (where most of the α cells are concentrated) of the pancreas. (3) By using cortisone-pretreated rabbits for assaying, it was found that a substance with glucagon-like activity by which hyperglycemia and lowering of the plasma FFA level can be induced was present in the blood of the portal vein after splanchnic stimulation. It is concluded from the above results that the greater splanchnic nerves appear to innervate the α-cells of the pancreas from which a glucagon-like substance capable of lowering the plasma FFA level is liberated into the blood stream after splanchnic stimulation.

本工作主要用兎做急性实驗,研究直接刺激内脏大神經外周端对血浆自由脂肪酸濃度的影响。結果如下: (一)在正常的不切除腎上腺的兎体上,刺激內脏大神經外周端对血浆自由脂肪酸濃度有不同的影响:有的使血浆自由脂肪酸濃度升高;有的降低;有的則基本不变。 (二)切除左侧腎上腺,刺激左侧內脏大神經外周端后,血浆自由脂肪酸濃度表現明显降低。若預先注射氯化钴以破坏胰島α細胞后,再做此項观察,血浆自由脂肪酸濃度的降低反应卽消失。在急性实驗狗身上,阻断左侧腎上腺靜脉血回流,刺激左侧內脏大神經外周端,亦可同样引起血浆自由脂肪酸濃度的降低,以及血糖濃度显著升高。切除胰尾部和胰体部以消除大部分胰島α細胞的作用后,再刺激內脏大神經外周端,上述反应卽消失。 (三)血液鉴定实驗指出,对切除腎上腺兎刺激內脏大神經后,門靜脉血血浆中有升高血糖物质存在,后者具有使血糖濃度升高和血浆自由脂肪酸濃度降低的作用。总結以上結果,可以认为,内脏大神經除支配腎上腺體质影响血糖和血浆自由脂肪酸濃度外,还极可能支配胰島α細胞,釋放类胰高血糖素物质,使血糖濃度升高及血浆自由脂肪酸濃度降低。
