The mammary excretion of suphamethomidine after intravenous and/or oral administration was investigated in cow. The results show that sulphamethomidine is bound to plasma proteins to a great extent (80~90%). Ay a dosage of 60 mg./kg. maximal concenration in plasma of this sulphonamide was reached 7-10 hours after oral dosing. The sulphonamide concentration in plasma slowly declined after both oral and intravenous administration (fig. 1, 2, and 3) The concentration of sulphonamide in milk was very low and the excretion was completed in 7 days after a single oral dose and 5 days after intravenous injection while in the case of blood plasma it was 11 and 7 days, respectively. In addition, the renal excretion of sulphamethomidine was investigated while under continuous intravenous intravenous infusion. The excretion ratios varies according to self depression (table. 1). Blockade of the tubular secretion with diodone lowered the excretion of sulphamethomidine. It is concluded that the renal excretion of sulphamethomidine in cows occurs by filtration by slight tubular secretion and also by a high rate of back diffusion.

The present study is involved with the prolactin secretion from anterior pituitary gland by ginseng saponin since it was handled down by tradition that ginseng might influence the milk secretion when it was given to nursing mother. To investigate the effect of saponin on the prolactin production or release from the anterior pituitary gland, cell culture study and whole animal studies were carried out. For the cell culture study, enzymatically dispersed anterior pituitary cells of rat anterior pituitary gland in HEPES buffers containing trypsin were used. Ginseng saponin was added to the culture media and the amount of prolactin produced in the cell culture media was determined by radloimmunoassay(RIA) technique. Dose-dependent increases of prolactin with ginseng saponin were observed, whereas, no change was observed without ginseng treatment. For the whole animal study, normal and castrated rats which previously cannulated into the heart via the right juglar vein were used. The prolactin concentration in plasma were determined by using the technique of RIA. In normal rats, prolactin concentration in plasma were elevated dramatically after 1 hour of ginseng saponin administration, whereas, instantaneous increases were observed in castrated rats. For prolactin assay by RIA, NIAMDD Rat Prolactin Kit and NIAMDD Rat Prolactin RP-1 were used as standard. The results indicate that ginseng saponins increase the release of prolactin from the anterior pituitary gland and production of prolactin from the cell in rats.

To find out the effect of oxytocin on somatic cell count and milk production, 12 primiparous and multiparous Murrah buffaloes were selected, immediately after the parturition, from the Institute's buffalo herd. These were divided into two groups of 6 each. Buffaloes of group I did not receive oxytocin injection (control); whereas, buffaloes of group II were administered oxytocin during early lactation (av. 42.50 days). The oxytocin injection was given in doses of 2.5 IU i.m. before the start of milking, to let down the milk, for a period of 5 days. Samples of milk from individual buffaloes were collected for 5 days before (Period I), during (Period II) and after (Period III) from both the group of buffaloes. Milk samples of A. M. and P. M. milking were composited in proposition to milk yields for analysis of milk constituents. Normal values of somatic cell counts in group I of buffaloes varied from 0.54 to $0.75{\times}10^{5}cells/ml$. Mean cytoplasmic particles and epithelial cells varied from 3.68 to $7.19{\times}10^{5}cells/ml$ and 0.13 to $0.54{\times}10^{5}cells/ml$. On percentage basis the epithelial and the total leucocyte count were 60 and 40. Total leucocyte count, in the study varied from 0.17 to $0.69{\times}10^{5}cells/ml$. The differential cell count of milk indicated presence of lymphocytes (16.50 to $61.16{\times}1000$), neutrophil (0.00 to $2.00{\times}1000$) and monocyte (0.00 to $18.16{\times}1000$). Somatic cell count (p<0.01) and epithelial cells (p<0.05) varied between buffaloes and between periods of study. Total leucocyte counts of milk were also significantly varied between periods (p<0.05). The change in fat, lactose, chloride, EC and NEFA concentrations during different periods of study, were highly significant, indicated diurnal variations in different buffaloes during different days of experiment. Administration of oxytocin resulted in increase in somatic cell counts of milk (p<0.01) due to the increases in total leucocyte count (p<0.01) during the treatment period. The differential cell count indicated that oxytocin administration increased lymphocyte number significantly (p<0.01). However, secretion of neutrophil, monocyte and cytoplasmic particles were not affected by oxytocin. Eosinophil and basophil cell, though present in few samples, remain unaffected by oxytocin administration. There was no effect of oxytocin on milk production, composition, pH, EC and NEFA concentration.

The relationship between udder maximum capacity (36-h accumulated milk yield) and the response of dairy cows (average producers) to thrice-daily milking was studied in 25 Friesian and 15 Jersey cows using the technique of half-udder study. Maximum half-udder capacity (acual yield) as well as whole udder capacity (estimated by udder measurements) was not altered significantly after 12-day thrice-daily milking period compared with a similar twice-daily period, although there was a positive response to increased milking frequency on secretion rate during this period. No effect of breed, season of the year or stage of lactation was observed on the above relationship. Hours-worth of capacity was higher with increased milking frequency, with Jersey than Friesian. These results suggest that udder capacity is not a limiting factor in increased milk production.

The human growth hormone (hGH) gene uder the control of the rat $\beta$-casein promoter gene was designed to produce transgenic mouse expressed hGH gene in only mammary gland. One hundred seventy two eggs microinjected were transferred to the oviducts of pseudopregnants and 43 offspring were delivered. By Southern blotting hybridization, 3 were transgenic with rat $\beta$-casein/hGH gene. The copy numbers of three transgenic founder were 1, 5, and 15, respectively. A radioimmunoassay was developed to quantitate the amount of expression of the hGH gene in mammary gland of transgenic mice. The amount of hGH was 13.3ng/ml in the lactating milk of one transgenic line, showing predominantly higher than 3.0ng/ml in milk of control mice. Therefore, our findings suggested that $\beta$-casein promoter may induce the tissue specific expression of structural gene.

In this review, we describe the patterns of known immunological components in breast milk and examine the relationship between breastfeeding and reduced risk of breast cancer. The top risk factors for breast cancer are a woman's age and family history, specifically having a first-degree relative with breast cancer. Women that have a history of breastfeeding have been shown to have reduced rates of breast cancer. Although the specific cause has not been elucidated, previous studies have suggested that breastfeeding reduces the risk of breast cancer primarily through two mechanisms: the differentiation of breast tissue and reduction in the lifetime number of ovulatory cycles. In this context, one of the primary components of human milk that is postulated to affect cancer risk is alpha-lactalbumin. Tumour cell death can be induced by HAMLET (a human milk complex of alpha-lactalbumin and oleic acid). HAMLET induces apoptosis only in tumour cells, while normal differentiated cells are resistant to its effects. Therefore, HAMLET may provide safe and effective protection against the development of breast cancer. Mothers should be encouraged to breastfeed their babies because the complex components of human milk secretion make it an ideal food source for babies and clinical evidence has shown that there is a lower risk of breast cancer in women who breastfed their babies.

In recent days, most of mothers prefer bottle feeding to breast feeding. Even mothers who started with breast feeding, change to bottle feeding in a short period. Many factors were reported causing the trend, but a significant influencing latter was revealed the mothers' perception that their breast milk wasn't enough for their babies. The purpose of this study were to identify how mothers of 30 years ago kept breastfeeding longer period for their child, and what were the diet they used in order to keep adequate breast milk secretion. The subjects of this study were 95 women who are over 60 years or older. Data were gathered by 13 authors by interview using structured questionnare. There were 16 questions related to subject's demographic informations and the specific recipe which they used, and 7 questions related to breast feeding techniques they used. Data were analyzed by SPSS/PC and content analysis. Results were as follows. 1. The subjects reflected that their milk secretion was enough to feed their tables. 2. More than half of the subject started breast feeding on the 3rd day after delivery and had continued breast feeding until they were pregnant again. 3. The subjects tried to eat as much rice and seaweed (MiYuk) soup as possible and didn't take any other specific diet during the breast feeding period. 4. The subjects didn't pay specific attention to the breast, general health. emotion, home environment. The only thing they did was being careful not to press breast when not feed. 5. Many subjects perceived that breast feeding made them healthy, and only 7% of subjects responded that they had some health problem during the breast feeding period.
