This paper deals with the distribution of Salmonella (S) infection on 4 herds in Kyungju and Taegu during the period from May to October 1986. Isolated Salmonella were examined for serotypes, antimicrobial drug resistance and detection of R plasmid. From 4 herds, 67 Salmonella were isolated from 51 samples (1.1%), and their serovar strains were S. typhimurium 6, S. derby 5, S. infantis 4, S. bareilly 4, S. dublin 3, S. anatum 2, S. montevideo 2 and untypable 41. In 4 herds, the incidence of drug resistance was 57.7-100% and transfer frequency of conjugative R plasmid was 96.1-100%.

Each of twenty blood samples taken from apparently healthy Korean cows was used to produce five different mixtures of autologous plasma and blood corpuscles such that their values of packed cell volume(PCV) lay between 10 to 50ml/100ml. The measurement of erythrocyte sedimentation rate(ESR) using 45 degree-angled Wintrobe hematocrit tube, 3mm bore, (45deg C-Wintrobe-ESR) was practised for the blood of various levels of PCV lowered. Correlation of the ESR to PCV showed curvilinear regression each in three levels of PCV under the ambient temperature of 10deg C, 20deg C and 30deg C. Correlation of the ESR to the ambient temperature showed linear regression each in five levels of PCV. The ESR increased with ascending ambient temperature, and magnitude of the increase of the ESR became greater as the level of PCV lowered. Correlation of the ESR to PCV showed curvilinear regression each in three levels of the ambient temperature, and the ESR was increased with decreasing PCV. The data were statistically analysed and a list of relative anticipated 45deg C-Wintrobe-ESR values for PCV and ambient temperature was presented.

For the comparison of surface fine structures in the proliferative forms of two major protozoan parasites, Toxoplasma gondii and Sarcocystis species in mammalian hosts, isolated from the artificially infected mice and from the naturally infected cattle, respectively, an SEM(Hitachi S-570) was applied to the fixed, dried and coated with gold ion on the microslide glasses. The tachyzoites of T. gondii from the peritoneal cavity of the mouse showed the crescent-like feature and measured as 5.57 micro m in length and 2.33 micro m in width, while the bradyzoites of Sarcocystis species from the heart muscle of slaughtered cattle was banana-shaped and measured 14.18 micro m in length and 2.85 micro m in width. On the surface of Sarcocystis species bradyzoite, a distinct elliptical micropore was identified in the high magnification observation of 60,000X, and it measured as 0.35 micro m in length and 0.18 micro m in width.

In order to study the marked variation of red blood cell sedimentation rate in some species of animals, the packed cell volume, volume percentage of erythrocytes in whole blood, was reshuffled of 20%, 40% and 60% using heteroplasma of chicken and goat, and the red blood cell sedimentation rate was measured in Westergren tubes at 27+-1 deg C and 8+-1 deg C. The values of packed cell volume (PCV) of goat and chicken were 40.7+-4.1% and 30.2+-2.2% respectively. The sedimentation rates of reshuffled red blood cell were settled faster at lower PCV than higher PCV, i.e. there was a reverse relationship between the sedimention rate and PCV. Red blood cells of chicken settled quickly, where as those of goat settled very slowly. Chicken red blood cell sedimented rapidly even in goat plasma, and goat red blood cell sedimented slowly in chicken plasma. These findings indicate that the plasma is not the only factor determining the rapid red blood cell sedimentation rate of chicken. The sedimentation rate of reshuffled red blood cell of chicken and goat were accelerated at higher temperature than lower temperature.

The measurement was investigated with 18 heads of fetus (60, 90, 120 days of gestation) and neonate in Korean native goats. The crown-rump length of fetuses at 60, 90, 120 days of gestation and neonate was 8.71, 20.83, 31.10 and 34.93 cm, respectively. The length of small intestine at 60, 90, 120 days of gestation and neonate was 32.28, 157.10, 303.52 and 475.06 cm, respectively. The length of large intestine at 60, 90, 120 days of gestation and neonate was 9.20, 37.70, 82.06 and 94.46 cm, respectively. The head length at 60, 90, 120 days of gestation and neonate was 2.93+-0.07, 6.67+-0.13, 8.84+-0.51 and 9.76+-0.44 cm, respectively. The width of the head at 60, 90, 120 days of gestation and neonate was 2.20+-0.13, 4.45+-0.11, 5.33+-0.20 and 5.51+-0.32 cm, respectively.

The anatomical structure of pelvic limb of thirty-one adult Korean native goats (Body weight : 14-17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. The hip bone consisted of the ilium, ischium and pubis which fused each other. The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator formen indexes were 53.84 and 54.77, respectively. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. The tibial shaft was sigmoid (S-) shaped and the popliteal notch was deep. There was a large nutrient formen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 (left) and 21.10 (right). The proximal extremity of the fibula was fused with the lateral condyle of the tibial but the distal one was observed independently as the malleolar bone.

This study has been carried out to investigate the augmenting or inhibiting effects of histamine, 5-hydroxytryptamine and their antagonists on the uterine motility. The uterine motility was represented by the magnitude of impulse and the frequency of uterine contraction which was counted by the number of waves on the recording paper. The inhibitory effect of phenoxybenzamine on the response to 5-hydroxytryptamine is the result of drug antagonism. Histamine stimlates or inhibits the motility of smooth muscle through H1 or H2-receptor. The uterine motility was increased through H1-receptor. Histamine induced relaxation by acting through H2-receptor.
