In the performance of the test,the original technic of Boyden (1951) has been followed with some modifications. Sheep cells can be preserved in the mproved Alsever's solution of Kendrick in refrigera- tor for 3 months without evident hemolysis. The test antigen,1:400 in ph 6.4 buffered saline,to be used for the sensitization of the tanned sheep cells, is stable for 2 months at -10℃.Reactions are recorded as “-”,“+”,“++”,“+++”,in different serum dilutions after the critetion set up by Stavitsky with a slight-modification....

In the performance of the test,the original technic of Boyden (1951) has been followed with some modifications. Sheep cells can be preserved in the mproved Alsever's solution of Kendrick in refrigera- tor for 3 months without evident hemolysis. The test antigen,1:400 in ph 6.4 buffered saline,to be used for the sensitization of the tanned sheep cells, is stable for 2 months at -10℃.Reactions are recorded as “-”,“+”,“++”,“+++”,in different serum dilutions after the critetion set up by Stavitsky with a slight-modification. 1:20 serum dilution has been considered as the minimal effective titre. The time for the occurrence of positive haemag- glutination reactions in rabbits after innoculation was in proportion to the degree of infection,averaged 17.3 days in the group with heavier infection (2000 cercariae each) and 23.7 days in the one with lighter infection (100 cercariae each). On the ayerage,stool hatching became positive in 37.3 days following infection for the former and in 42,6 days for the latter. Therefore,this reaction hasita value of early diagnosis in experimental schistosoma infection. A single haemagglutination test in each of the 239 cases of schistosomiasis revealed a positive rate of 92.9%. The effective titers for serum dilution most commonly encountered in chronic cases were found to be laying between 1:40-1:320,with a highest value of 1:2560,while in acute cases.1:640-1:20,480.All the 28 mormal persons and 24 non-schistosoma medical cases showed negative reactions.In one case of subacute bacterial endocarditis with neither de- finite history of exposure nor any clinical evidence of schistosoma infection,yet the reaction was positive (similar with other serological tests as cercariae membrane,circumova precipitin and carmine floccu- lation reactions).Whether the bacterium in question (not isolated) shares common antigenic fractions with schistosoma worms should call for further attention. No cross reactions in cases of leishmaniasis. amoebiasis,giardiasis,paragonimiasis,clonorchiasis. ancylostomiasis,filariasis,ascariasis and taeniasis have so far been encountered. In conclusion,it has been pointed out that the chief advantage of thins test lies in the high serum- dilution titre,which far surpasses other serological methods used in this infection as complement fixation test,etc. Thus,if not only gives us a means to titrate the antibody content of the serum under examination but also enables us to follow up the course of the disease.

Rats with 1,2,3,and 4 injections were killed 7 days afterwards.Pieces of liver tissue were taken from the left anterior lobe of the rats from both experimental and control groups.Paraffin sections were prepared from materials fixed in:(1)Susa or Stieve's for Heidenhain's Azan staining;(2)Regaud's for Bensley's acid fuchsin-methyl green staining of mitochondria;(3)cold Carnoy's for methyl green-pyronin staining of ribo- nucleic acid (RNA),with control sections extracted with 20% perchloric acid or 0.17 M NaCl at 56℃ for 2 hrs.;(4)Carnoy's for Yakovlev's ((?)) and Barrnett- Seligman's methods for protein-bound SH-group,with control sections blocked with 0.1M monoiodoacetic acid;(5)Formol-alcohol for Hotchkiss's periodic acid-Schiff's (PAS) reaction of glycogen,with control sections treated with salivary digestion;(6)cold ace- tone for alkaline phosphatase (ALP);and (7) 10% neutral formalin for frozen sections and Sudan Ⅲ testing for fats. After CCl_4-intoxication,during the development of cirrhosis,most of the parenchymal cells degenerated and finally became necrotic.Free fat droplets and hyperplastic fibrous tissues accumulated in the necrotic regions.The liver lobules thus were destroyed and blood sinuses were engorged with blood cells.Surviving cells showed compensative hyperplasia and were isolated into nodules by the developing fibrous tissues.Cirrhosis developed in all the rats treated with CCl_4. The parenchymal cells showed a progressive changes during the development of cirrhosis.There was an increase of fat droplets and a decrease of the number of mito- chondria in the cytoplasm.The mitochondria fragmented into granules or fused in a mass.There was a progressive decline in the content of RNA and glycogen,but an increase of the ALP activity.Those cells showing compensative hyperplasia enlarged in size,and their number of mitochondria,RNA and glycogen content progressively in- creased. Small-sized cells appeared in the necrotic regions among the fat droplets,necrotic cells and fibrous tissues.They decreased in number as the fibrous tissue developed. These cells contained mitochondria and showed positive reactions of PAS,RNA and ALP.Their origin was discussed and their relation to the formation of collagen fibers needs further investigation.

Acute experiments were carried out on rabbits with the pancreatic duct ligated from one day to two months previously. The change of the concentration of free fatty acid (FFA) in the plasma was observed after electrical stimulation of the peripheral ends of the dorsal and ventral subdiaphragmatic vagus nerves and a correlated histological and histochemical examination of the pancreatic tissue was also undertaken. The results were as follows: The concentration of the plasma FFA in normal rabbits was markedly increased after vagal stimulation. After ligation of the pancreatic duct, however, the result of stimulation gradually changed with the length of the ligation period: In the first 2 days after ligation, both increase and decrease were observed with about the same frequency; 3—21 days after ligation, the result was more frequently a decrease; 23—60 days after ligation, the effect was uniformly a decrease. Histological and histochemical examination revealed that there was a great deal of degeneration in the parenchyma after ligation of the pancreatic duct and that about 3 weeks after ligation the acinar cells had atrophied and there was an abundant infiltration of fibrous tissue. The lipase granules fn the acinar cells were present after 2 days of ligation. From the third day on, the lipase reaction began to disappear entirely. The alkaline phosphatase reaction was still positive in the cells of the dilated ductules and the islet cells remained normal after 2 months of ligation. It is supposed that the increase and decrease of the plasma FFA after the vagal stimulation might be due respectively to two separate factors in the pancreas. The factor that causes the increase and disappears after atrophy of the parenchyma, might come from the exocrine system of the organ, while the origin of the factor which causes the decrease is not yet clear. Further work is obviously needed in this connection in order to elucidate the exact mechanism.

本工作以兎为实驗对象,在結扎胰导管后1—60日等不同日期,进行急性实驗,电刺激腹、背侧膈下迷走神經外周端,观察血浆自由脂肪酸濃度和胰腺組織学及組織化学的变化。結果如下: 刺激未結扎胰导管兎的膈下迷走神經外周端,血浆自由脂肪酸濃度表現为升高反应。結扎胰导管后不同日期刺激迷走神經,則反应形式发生了明显的阶段性变化:在結扎的初期(1、2日),除升高反应外,有的还表現有降低反应;随着結扎日期的延长(3—21日),仅偶尔出現升高反应,而多数則表現为波动及降低反应;在結扎胰导管3周后(23—60日),全部表現为降低反应。 組織学和組織化学檢查显示:結扎胰导管后,胰腺腺泡細胞逐漸破坏,至3周左右,一般都已消失,代之以增生的結締組織。腺泡細胞內脂肪酶于結扎后1、2日內仍呈阳性反应,而于3日后郎呈阴性反应。导管系統在結扎后卽行扩張,小导管壁硷性磷酸酶在結扎后60日內均呈阳性反应。胰島細胞在結扎胰导管2月內仍正常。根据以上結果,似可推想,兴奋迷走神經有使血浆自由脂肪酸濃度升高和降低的两种作用。在不結扎胰导管情况下,刺激迷走神經所引起血浆自由脂肪酸濃度的升高反应,可能是由于升高作用占优势;結扎胰导管后,在胰...
