This is a study on the light microscopical and electron microscopical findings of the morphological changes of the liver of Korean native gout injected with toxin (culture filtrate) of Clostridum perfingens which was isolated from Korean native cattle. Decreased number of glycogen granules, swelling and destruction of mitochondria, proliferation of smooth-surfaced endoplasmic reticulum, dispersal of thready agranular membranous structure and appearance of secondary lysosome were recognized in the hepatic cell cytoplasm.

The disease syndrome characterized by acute vomiting and diarrhea with high mortality was prevalent in Korea [R.]. The agent present in the faces of dogs associated with this syndrome had the characteristic feature agglutinating red blood cells that was specifically inhibited by anti-CPV (canine parvovirus) reference dog serum. This also showed the serological identity with the reference CPV antigen in immuno-diffusion. Electron micrograph of the material revealed parvovirus particles with the size of 20nm and icosahedral structure. These results clearly indicated that CPV was the primary cause of canine epidemic prevailing in 1981 in Korea [R.].

Serum glumatic oxaloacetic transminase (GOT), lactic dehydregenase (LHD), and alkaline phosphatase (ALP) activities were determined in 5 Korean native cattle to obtain the base line of blood enzyme activities in relation to the gestation stage. Serum GOT activities showed an increasing tendency with the course of gestation period. Serum LDH levels were withing normal range through all the stages of pregnancy, and the slight increase in serum ALP activities was acknowledged at the 2nd and 3rd stage of gestation.

This experiment was performed to determine the effect of Xylazine and Ketamine hydrochloride for sedation in deers. Xylazine and ketamine hydrochloride were given intramusculary to 32 deers (sika deer 7, red deer 11, elk 6, pere david deer 3, and reindeer 5). Ketamine hydrochloride was injected 30 minutes after administration of xylazine. The recovery from sedation of combined anesthesia was remarkably fast compared with xylazine alone.
