The levels of activities of amylase, lipase and trypsin in both the pancreatic tissue and serum of 18 species of vertebrate animals were measured and enzymologically compared with each other. 1) The value of amylase in the pancreas of experimental mammalia has been found decreasing in the order pig, rat, dog, cat, rabbit and cow; that of pancreatic lipase has been found decreasing in the order of pig, dog, cat, rat, rabbit and cow; and that of trypsin has been found decreasing in the order of pig, cow, dog, rat, rabbit. Thus the value of all the above three kinds of enzymes were observed highest in pig, but in cow amylase and lipase were observed lowest while trypsin were observed considerably high. 2) In view of diets, the comparatively high values of pancreatic enzyme were observed in the ommivorous animals such as pig, rat, dog, while the values observed low in the herbivorous animals, such as cow and rabbit. 3) In the bovine, the values were observed moderately high except lipase which were found comparatively low. 4) In the Reptilia and Amphibia such a mud turttle and frog, the values were shown in similar measure with each other, that is, the pancreatic amylase and trypsin were observed considerably high while the lipase was found low. 5) In the species of Reptilia such as a viper and snake, the activities of pancreatic enzymes were not detected. But in the tissue of liver, stomach, activities of the enzymes were found considerably high. Lacertilia animals such as lizard the values of pancreatic enzymes were little observed. 6) In the fish in which the pancreatic tissue is scattered in the liver, the pancreatic enzymes were found in the liver tissue considerably higher than in the other tissues but lower than in the warm-blooded animals, especially the lipase was lower. 7) In generally the values of serum amylase and lipase were observed higher than those of man; and even in the cold-blooded animals in which the values of pancreatic enzymes were shown low or none, the values were also observed high. 8) The above three kinds of pancreatic enzyme values of those experimental animals have shown a tendency of higher degree in higher taxa than in lower taxa according to taxonomical order. 9) In view of tissue, the pancreatic cell was observed large in the mammalian animals such as rat and pig and cytoplasm was also abundantly contained in the acinous cell; and the bovine and the snake haave the pancreatic cells of the similar rosette form the comparatively large acinous cells of long rhombic form in the comparatively large acinous cells of long rhombic form in which the spindle shaped neucleus and the abundant cytoplasm were contained. In the fish the pancreatic cell were found scattered in the liver in which the very large pancreatic islet were found.

Comparative studies were made on some sulfonamides, used individually and combined with parasympatholytic agents as regards (1) the absorption rate through isolated rat small intestine (in vitro), (2) the absorption rate through rat small intestine (in vivo), and (3) the blood concentration of sulfonamides were examined by its oral administration with each combined drug to rabbits, and the following effects were found, parasympatholytic agents inhibit the absorption of sulfonamides from the small intestinal tract. Comparison of the inhibitic efficiency of parasympatholytic agents is as follows: oxazepam, oxyphencyclimine hydrochloride, probantheline bromide, atropine sulfate (The examples are from the weakest to the strongest). Decrement of the absorption rate of sulfonamides is as follows: sulfadiazine, sulfathiazole, sulfamethoxypyridazine, sulfadimethoxine, sulfamerazine, sulfamethazine (The example are from the strongest to the weakest). Additionally, it is assumed that if the combined drugs were absorbed from the small intestine in the original form, those inhibitic effects should be best regarding to their sulfonamide per parasympatholytic agent combined rate "25:1" than to their any other rates.her rates.

Aconitum Uchiyamai NAKAI "geu-neul-dol-che-gi"(Ranunculaceae), is geographically distributed only in Korea. An aconite collected at Mt. Dukwoo, Kangwon-Do flowers with white color in October. The aconite is different from Aconitum Uchiyamai NAKAI from the point of anatomical and morphological views in transplanted and collected aconites. Being a new variety of Aconitum Uchiyamai NAKAI, this aconite is anounced under the name of Aconitum Uchiyamai NAKAI var. albiflorum CHUNG et RIM, "Hin-geu-neul-dol-che-gi" called in Korea. Aconitum Uchiyamai NAKAI var. albiflorum CHUNG et RIM Differt a planta Aconitum Uchiyamai NAKAI per colorem album.

Alkalinity of pharmaceutical containers is to be highly influenced for liquid pharmaceuticals. The criteria of the alkalinity of ampoules and vials used as pharmaceutical containers is established in the Korean Pharmacopoeia. However, the criteria of general containers for liquid pharmaceuticals is not eatablished in the Korean Pharmacopoeia. Therefore, we tried to perform comparing test for domestic products and foreign products of following group: 1) vials 2) general containers for liquid pharmaceutical 3) general containers for tablet pharmaceuticals It was found that the domestically produced vials were good enough for criteria, while almost fifty percent of non-established containers was unsaticefactory.
