Purpose: We analyzed climacteric symptoms, bone mineral density (BMD), serum estradiol ($E_2$) and follicle stimulating hormone (FSH) to identify the health benefits of meridian massage in perimenopausal women. Methods: There were 16 women in the experimental group and 17 people in the control group. Meridian massage was performed for 4 weeks, 3 times a week for 20 minutes each session. The data were collected pre-treatment, posttreatment and 4 weeks after treatment. SPSS/WIN 11.5 was used for data analysis. Results: After meridian massage, there were significant differences in climacteric symptoms (U = 65.50, p = .011) and BMD (U = 65.50, p = .011) between the two groups. The E2 level showed a significant difference between the two groups pre- and posttreatment (U = 75.00, p = .028). FSH showed a significant increase when measured at 4 weeks after the treatment as compared with the amount when measured post-treatment within the control group (z = -2.249, p = .025), experimental group showed a stable change in FSH. but there was no significant difference between the groups. Conclusion: In this study, we confirmed the effects of Meridian massage in decreasing climacteric symptoms, inhibiting the decrease of BMD and stabilizing serum hormone in perimenopausal women. Therefore, it can be considered for use as a nursing intervention for health management in perimenopausal women.

These studies were carried out to establish an effective and practical system for commercialization of embryo production techniques by analyzing several factors influencing in vivo embryo production in Korean native cattle. In vivo embryos were flushed 226 times from 128 donors. The results obtained in studies on the factors influencing in vivo embryo production were as follows : 1. There were no significant differences in the number of total recovered, fertilized, transferable and freezable embryos among the hormone doses(FSH-P, 28∼34mg; SUPER-OV, 75IU) used for superovulation. However, over 30mg doses of FSH-P showed a slightly higher effect than others. 2. There were slight decrease in the number of fertilized, transferable and freezable embryos in 3 times repeated superovulation. But there were no significant differences among 1, 2 and 3 times repeated superovulations. 3. Age of donors did not affect the number of transferable and freezable embryos, but the number of fertilzed embryos were highest in 2∼3 years old donors and were lowest in 8∼9 years old donors(P<0.05). 4. Season had a significant effect on the production of embryos(P<0.05). the embryo production, and the number of fertilized, transferable and freezable embryos were most effective in summer and follow by spring, autumn and winter. 5. The number of transferable and freezable embryos was highest in donors flushed at 7∼8 days after estrus(P<0.05).

Domestic bitches are non-seasonally monoestrus; spontaneously ovulate only once or twice occurs at anytime of the year. Estrus induction has been applied infrequent estrus, misleading ovulation, mating difficulties, failure to conceive after normal mating, pregnancy failure and biological research. Protocol of estrus induction which included variable hormones such as FSH, GnRH, and PMSG have been applied for the last decades. Recently, Bromocriptine, one of anti-prolatin/dopamine agonist has been occasionally applied for estrus induction. The study was carried out to investigate the effective method for the induction of estrus in bitches using different hormone treatments, and the initiation time of estrus from hormone treatment by assessments of cytological observation and blood plasma progesterone concentration. A total of 54 bitches on anestrus were selected for the study and divided randomly into 8 treatment groups as follow. Control, natural estrus; FSH (L), FSH (1.5 mg/kg, twice a day, $Falltrophin^{(R)}$, Vetrepharm); FSH (H), FSH (3.0 mg/kg, twice a day); GnRH+FSH, GnRH (5 ug/kg, once first day, $GNADON^{(R)}$, Dongbang)+FSH (3 mg/kg, SID); PMSG, PMSG (50 IU/kg, every third day $FOLLIGON^{(R)}$, Intevet); GnRH+PMSG, GnRH (5 ug/kg, only first day)+PMSG (50 IU/kg, every third day); GnRH, GnRH (5 ug/kg, only first day); Bromocriptine, bromocriptine (0.3 mg/kg, SID, $Parlodel^{(R)}$, Novartis). The bitches were evaluated clinical sign, cytological exam and $OVUCHECK^{(R)}$ Premate for assessment of estrus induction. Estrus induction rates were significantly (P<0.05) higher in GnRH+PMSG (100%) compared to others. PMSG and GnRH+PMGS (87.5 and 100%) and Bromocriptine (77.8%) were higher than others except GnRH+PMSG. Analysis of vaginal smear has proved to be effective a correct assessment of estrus induction with assay of progesterone concentration by $OVUCHECK^{(R)}$ Premate. Proestrus initiated by the $6^{th}$ after induction in most case. In conclusion, bromocriptine is an effective drug for estrus induction in bitches and assay of progesterone concentration by $OVUCHECK^{(R)}$ Premate with examination of vaginal smear that should be useful to detection of estrus induction of estrus induced bitches.

The culture of preantral follicles has important biotechnological implications through its potential to produce the large quantity of oocytes for embryo production, transgenesis research, conservation of rare breed, and a potential source of ovarian genetic material. The present study was conducted to establish the optimal conditions of in vitro culture for intact bovine preantral follicles; and to examine the developmental ability of oocytes derived from the in vitro-grown preantral follicles; and to investigate the effects of various concentrations of FSH and LH on these processes. Bovine preantral follicles (150 $\pm$ 1.2${\mu}{\textrm}{m}$), surrounded by theca cell, were isolated enzymetically and mechanically from ovarian cortical slides in Leibovitz L-15 medium containing 1 mg/$m\ell$ collagens and 0.2 mg/$m\ell$ DNase I and cultured for 25 days in the presence of different concentrations of bovine FSH and LH in $\alpha$MEM medium with insulin, transferrin, and selenite. The survival was tested by frypan Blue and Hematoxylin. The survival and growth rates of follicles were higher in FSH treatment groups than these in control (P<0.001), but there were no significant differences between the LH treatment groups and the control. In 25 days, the survival and growth rates of follicles in FSH and LH treatment group (50%, 300$\pm$1.0${\mu}{\textrm}{m}$) were higher than in FSH treatment group (40%, 244$\pm$0.5${\mu}{\textrm}{m}$) and the control group (25%, 160$\pm$ 1.0${\mu}{\textrm}{m}$). Fifty-five percent of healthy antral follicles were obtained, and 60% of the oocytes complete meiotic maturation to the metaphase II stage. Twenty-two percent of the mature oocytes underwent cleavage, and 9% developed to the blastocyst stage. In this study, in vitro-grown oocytes (111 $\pm$ $1.5mutextrm{m}$), under our culture conditions, were not equivalent in size to the in vivo-grown oocytes (130$\pm$1.3${\mu}{\textrm}{m}$). Therefore, these results suggest that bovine preantral follicles with intact theca cell can grow to the antral stage in 25days, and that oocytes from those follicles can acquire the meiotic competence and normally undergo fertilization and development to the blastocyst stage. However, the developmental capacity of in vitro-grown oocytes is presumably not comparable to those of the in vivo counterparts.

The objectives of the present study were to select an effective basic medium including its hormone and protein supplementation for IVM of oocytes of indigenous zebu cows. The ovaries of cows were collected from slaughter house and the follicular fluid was aspirated from 2 to 8 mm diameter follicles. The COCs with more than 3 cumulus cell layers and homogenous cytoplasm were selected for maturation. The oocytes were matured in media for 24 hrs at $39^{\circ}C$ with 5% $CO_2$ in humidified air. The maturation of oocytes was evaluated by examining the presence of first polar body under microscope. An efficient basic medium was determined after culturing COCs in either TCM 199 or SOF medium in Experiment 1. An efficient hormone supplementation was determined after culturing COCs in either FSH or gonadotrophin supplemented TCM 199 in Experiment 2. An efficient protein supplementation was determined after culturing COCs in either FBS or Oestrous cow serum (OCS) supplemented TCM 199 in Experiment 3. The oocyte recovery rate per ovary was 3.35. The overall rate of IVM was 74.6%. The maturation rate was $75.5{\pm}3.9$ and $62.2{\pm}20.2%$ in TCM and SOF medium, respectively (P>0.05). The maturation rate of oocytes was significantly higher ($76.6{\pm}13.2%$) in FSH supplemented medium than gonadotrphin supplemented counterpart ($69.7{\pm}10.8%$) (P<0.05). The maturation rates of oocytes were $81.7{\pm}12.9$ and $85.7{\pm}12.7%$ in medium supplemented with FBS and OCS, respectively (P>0.05). In conclusions, both TCM 199 and SOF supplemented with either FBS or OCS, and FSH may be used as medium for IVM of indigenous zebu oocytes in Bangladesh.

The objectives of this study were to investigate the ovarian responsiveness of juvenile calves to exogenous gonadotropin treatments and to establish the oocyte retrieval technique for prepubertal heifers. Three 78-day-old calves were treated with 4 doses (40, 30, 30 and 30 mg) of FSH (Folltropin V) at 12 h interval up to 229 day-old. Surgical oocyte retrieval was performed 24 h after the last injection of FSH. Calves with good ovarian responses to FSH treatment had an average ovarian size of $5{\times}3$ cm compared to $3{\times}2$ cm in the less-responsive animals. Large variations were observed in the number of total follicles ($51{\pm}45$), aspirated follicles ($39{\pm}36$), oocytes recovered ($23{\pm}25$) and usable oocytes recovered ($11{\pm}19$) during 78 to 229 day-old. Oocytes derived from prepubertal calves had significantly lower maturation rate than those from cows (34 vs. 100%, p<0.05). Mean diameters of calf oocytes ($144{\pm}1{\mu}m$) and ooplasm ($110{\pm}1 {\mu}m$) were significantly lower than those of cows ($149{\pm}1$ and $25{\pm}1{\mu}m$, respectively). The diameter of the ooplasm also increased significantly after in vitro maturation (IVM) ($108{\pm}1$ vs. $112{\pm}1{\mu}m$). However, further studies are required to optimize the IVP system for the oocytes derived from prepubertal heifers.

This study was conducted to research the endocrine mechanisms of postpartum anestrus and determine if the morphology of the CL could be related to function in Korean native goats. At parturition 48 goats were assigned to a nonsuckled group and a suckled group. Serum concentrations of luteinizing hormone(LH), follicle stimulating hormone(FSH), prolactin(PRL), estradiol-17$\beta$(E2) and cortisol were measured at various times after parturitionin the goats. The corpora lutea of pregnancy were examined by a light microscope on the 6th hour and the first, 3rd, 10th, 11th, and 21st days after parturition. The results were summarized as follows : Mean serum LH concentrations were lower after parturition in all treatments and increased gradually with the intervals after parturition(P<0.01). These values did not differ between groups. The levels of serum FSH were lower after parturition and tended to increase gradually between 2 and 21 days. The levels of serum FSH are not significantly different between the groups of goats. Two days after kidding mean levels of serum PRL began to fall in nonsuckling goats but increased in suckling goats. During 3 weeks serum PRL concentrations were different between nonsuckling and suckling goats(P<0.01). Three days after parturition the levels of serum E2 decreased in all treatments. From parturition to day 21 serum E2 concentrations were greater in nonsuckling than in suckling goats(P<0.01). At the sixth hour after parturition the structure of the CL was well preserved. At days 1 and 3 the blood vessels were sparcely distributed, whereas, at days 1 and 3 the blood vessels were sparcely distributed, whereas, at days 10, 11 and 21 tortuous larger vessels with thick walls were observed on the luteal tissue. At days 1, 3, 10, 11 and 21 after parturition the CL of pregnancy showed degeneration and the proportion of tissue occupied by intercelluar substances increased at days 21 postpartum. In conclusion, the present study has shown that regression of the CL of pregnancy is accelerated in the period after parturition and effectively completed within three weeks postpartum.

The present study was carried out to investigate effects of gonadotropin, age of donor, day of estrus cycle gonadotropin injection started and season on embryo production after superovulation in dairy cattles. Embryo collection records were obtained from 177 embryo donor collections from 98 Holstein cows aged from 3 to 9 years during 4 years(1993~1996) at National Livestock Re-search Institute. Superovulation was induced by injections of 3 gonadotropins(FSH-P, FOLLTROPHIN-v* or SUPER-OV*) beginning on days 9 to 14 of the estrus cycle. Em-bryos were collected from donors using a nonsurgical technique on days 6 to 8 after insemi-nation. The results were as follows ;Number of total and freezable embryos per donor cow was affected by gonadotropin(P<0.01). The more number of total and freezable embryos wereobtained by use of FOLLTROPHIN-V (13.2, 7.4) or FSH-P (11.0, 5.7) than SUPER-OV* (5.0, 2.4). Age of donor, the day that gonadotropin was started or season didn't affect total or freezable embryos(P >0.05).
