Epizootics and sporadic outbreaks of the cattle disease characterized by fever, stomatitis and dysphagia were observed in Korea [R.] in September through November, 1982. The main lesions of the disease were defined as edema, hemorrhage, degeneration and necrosis of the oral mucosa and musculatures of the esophagus and laryngopharyngeal area, and abomasum. The serum samples of the cattle with typical symptoms showed significant positive titer of the antibodies against Ibaraki virus.

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.

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.
