The author observed the effect of x-ray irradiation on the development of the mandible in the fetuses and growing albino rats. The fetuses were irradiated on the 7½th day of gestation, 100, 200, 300, and 400 rads of x-ray respectively. The experimental animals were sacrificed on the 18½th day of gestation, and first week, second week and third week after parturition. The results were as follows; 1. The mandible of the 18½th day fetuses showed irregular bone trabeoulae, osteoclasts and osteocyte degeneration on the 300 and 400 rads x-ray irradiated fetuses. 2. In the mandible of the first week rats, there was marked osteocyte degeneration and a lot of osteoclast. 3. In the mandible of the 2nd and 3rd week rats bone remodeling was evident. The 3rd week rats also showed alteration of blood vessel wall.

The purpose of this experiment was to investigate the protein profiles in the placenta of Korean native cows(KNC) transferred cloned embryos and KNC artificially inseminated placental tissues were collected from the cows after cesarean section around parturition, and placental proteins were analyzed. Using two dimensional polyacrylamide gel eletrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. (omitted)

The erythrocyte sedimentation rate (ESR) test could be applied well in clinic of men, horses or dogs. But the ESR test was not applied to clinic ruminants except for buffaloes since it was too low measure. To overcome this problem angled tube method was developed. This method was found to be useful for making diagnosis and prognosis. The results were summarized as follows. 1. In the early pregnancy condition, corrected ESR did not changed when compared with normal valures. 2. In the middle pregnancy condition, corrected ESR was increased when compeared with normal valures. 3. In the latter pregnancy condition, corrected ESR was increased when compeared with normal valures. 4. After parturition condition, corrected ESR did not changed when compeared with normal valures.

Nine immature 30-day-old female rats were injected sc at 0800 hr with pregnant mare serum gonadotrophin(PMSG) to induce ovulation and mating. Fifty-six hours later the animals were placed with mature male rats overnight (one female and one male). Five of 9 immature female rats treated with PMSG were pregnant and allowed to maintain the pregnancy to term. Three of 5 pregnant rats were failed to maintain pregnancy to term. Two of 5 pregnant rats seemed to be developed normally and increased abdominal enlargement as pregnancy progresses, but did not occurred parturition on day of 43 or 48 of pregnancy, respectively. On day 44 or 49, pregnant rats were killed and examined uterus and ovaries. There was no fetus but approximately 50∼60ml. of mucopurulent fluids were accumulated in the uterine cavity and 40 or 42 corpora lutea persisted in the ovaries. Pyometra was developed after coitus in PMSG-treated immature female rat.

An eight years old female barbary sheep (Ammotragus lervia), which bred at the Gwangju Uchi Park Zoo had shown anorexia, depression, respiratory problem for several weeks after parturition. In necropsy, extensive necrotizing pneumonia was found with severe immunocytes infiltration in the alveolar spaces and bronchioles. Pulmonary pleura were thickened with fibrin and inflammatory cells. Bacteria were isolated from lung and identified as Streptococcus equi subsp. zooepidemicus (SEZ) by biochemical tests and PCR on sodA and gusA genes, though seel gene was not detected. Isolation of zoonotic SEZ in public place such as a zoo should be emphasized for the public health mangagement.

Glycogen and alkaline phosphatase were studied histochemically in the placenta of the golden hamster (Mesocricetus auratus). The results were summarized as followings: 1. The histochemical distribution of glycogen and alkaline phosphatase was described in the various cells of both the placenta and uterus from implantation (5 days past coitum) parturition. 2. Glycogen appeared in the extraembryonic ectorm of the implanting ovum and increased gradually in the ectoplacental cone with the development of the placenta. 3. Glycogen granules began to accumulate in the labylinthine trophoblast of chorioallantoic placenta at 10.5 days and in the endodermal cells the visceral yolk sac sac at 10 days, respectively, and in these both cells glycogen increased gradually until the 13 days post coitum and after this time decreased progressively. 4. Alkaline phosphatase activity was high in the labyrinth, junctional zone and decidua, but was not observed in the yolk sac and trophospongium.

This paper aims at investigating the realities of puerperal period of Korean women, chiefly in the city of Seoul, on the basis of their living standard, schooling caree by age groups, to contribute to the improvement in health of mother and child. In this paper in which the writer, aming 492 women in Seoul a subject of this investigation and giving them 34 items of questionnaires, has studied their concern and practices to recover their health during a lying-in period, and drawn a conclusion as follows : Though their place of childbirth and food they take during the period are varied according to their standard of living, their practices and managements after parturition are true to the conventional usage which is far from modern scientific methods. Problems for the better management during puerperal period are : 1. to have expactent and nursing mothers better educated in their antenatal care ; 2. to let the family planners have more understanding about the problems of puerperal period ; 3. to make those who are concerned study on the problems interdependent between puerperal period and pregnancy and child birth.

The longitudinal changes on human milk intake of exclusively breast-fed infants(boys=15, girls=12) from 0.5 to 6 months after parturition have been studied by test-weighing method in Cheongju and Anseong area. Infant milk intake per day tended to increase during lactation. The mean intake at 0.5, 1, 2, 3, 4, 5, and 6 months were 532, 695, 734, 756, 785, 767, and 710g, respectively. The average intakes were 752 and 660g for boys and girls, respectively. The overall mean intake was 711g/day. The milk intake between boys and girls at 1, 2, 4 months, and mean value was significantly different(p<0.05). Infant milk intake had a significant positive correlation with human milk volume of lactating women, but no correlation with maternal age, weight before delivery, height, and birth weight.

This study was undertaken to investigate congenital microphthalmia occurred at a pig farm in Gyeongbug province. These microphthalmic piglets composed of 20 piglets farrowed by three different sows(1, 11 and 8 piglets by No.1, 2 and 3 sow, respectively) that were apparently normal during pregnancy and after parturition. Attempts were made to know epidemiological findings and histopathological changes of these piglets and the results were summarized as follows; 1. One piglet from No. 1 sow exhibited staggering and incoordination and remained alive, but 19 piglets from No. 2 and 3 sow died between 3 and 20 minutes after birth. 2. In histopathological finding, hypoplasia and edema of all organs were observed in all piglets, and significant of lesions related to infection of microrganisms were not observed. 3. The cause of microphthalmia was considered as hypovitaminosis A in the sown intaked only barley barn before and during early pregnancy.

In this report, we described a case of acute colic with uterine rupture in a Thoroughbred broodmare during parturition. A 14-year-old broodmare showed acute colic characterized by rolling just after delivering of a healthy foal. Large intestine was prolapsed through vulva, contaminated with soil and its serosa was heavily damaged. We performed a euthanasia according to the owner's request. Post mortem examination revealed about 15 cm rupture on ventral side of the uterus. In addition, the orphan foal follow his owner after necropsy on his dam.
