Experimental hypocalcemia was induced in normal goats by intravenous infusion with various concentration of Na2-EDTA solution. Progressive depression of reflexes and body temperature, paresis, and cardiac arrest were observed in 2 groups infused with 4% and 8% EDTA solution. When plasma Ca decreased to 6mg/100 ml or below, sinus bradycardia or tachycardia and prolongation of OT interval were shown, while atrioventricular block was noted in which case the plasma Ca level decreased to 4 mg/100ml or below. Fibrillation and cardiac arrest were evident in which case the plasma Ca level decreased to as low as 3mg/100ml.

A survey of ascariasis in pigs (960) at 3 processing plants in Seoul, Daegu and Busan, Korea [R.] demonstrated that ascariasis was a common problem in pigs. Ascaris lessions (white and generalized fibrosis) were observed on 547 livers (57%) of the pigs. The greatest occurrence of Ascaris lesions (68%) were found in pigs from the Busan Korea [R.] area.

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.

This article outlines a pathway to develop the business case for One Health. It describes the origin and development of One Health and then identifies five potential areas where One Health can add value and reduce costs. These are: (1) sharing health resources between the medical and veterinary sectors; (2) controlling zoonoses in animal reservoirs; (3) early detection and response to emerging diseases; (4) prevention of pandemics; and (5) generating insights and adding value to health research and development. Examples are given for each category along with preliminary estimates of the potential savings from adopting the One Health approach. The literature reviewed suggests that one dollar invested in One Health can generate five dollars worth of benefits and a global investment of US$25 billion over 10 years could generate benefits worth at least US$125 billion. Conservation implications: the time has come to make the bigger case for massive investment in One Health in order to transform the management of neglected and emerging zoonoses and to save the lives of millions of people and hundreds of millions of animals whose production supports and nourishes billions of impoverished people per annum.

This is an investigation on the detection method of Fasciola eggs from positive cattle feces in the intradermal reaction method with labor saving composition of sieves and Kim's sedimental tube method. The 3rd type of tube in the 3 kinds of sedimental tube had the highest recovery rate of Fasciola eggs. A-2, A-3, B-3 and C-3 type by Kim's sedimental tube method had the recovery rates of eggs in the 1st drop ranging from 99-100% and A-1, B-2, C-2 as 71-91%. These type of tubes were useful to detect Fasciola eggs and to shorten the time of the diagnostic procedures. The Kim's sedimental tube method showed hish recovery rates and convenient procedures as compared with other detection methods reported.

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.

A massive mycetoma was observed in the abdominal cavity of a 3-year-old spayed female Labrador Retriever dog which originated from France. The mycetoma lesion involved adhesion with one-half of the spleen, several portions of the small and large intestine, and the diaphragm. Histologically the distict hypertrophy of the intestinal muscle layer and wide spread deposition of the hemosiderin through the affected abdominal organs and thrombosis of aplenic arterioles with athematous change were recognized as persistant. There were also debilitating changes in the affected organs. From the histological appearance of the fungal colonies it was presumed that the causative fungus was Allescheria boydii.
