Purpose: Endometriosis has been thought to be related with blood stasis in uterus. Pinelliae Tuber is a herb which has effectiveness of dispelling phlegm which can be transformed into blood stasis, so is used in gynecology blood stasis-desease. Therefore in the present study, the effects of Pinelliae Tuber on endometriosis were investigated. Also retention enema therapy acts on the limited part directly, so is used frequently in gynecology clinic. This study was to examine the comparative effects on the surgical induction of endometriosis in the rat between orally and rectally administered with Pinelliae Tuber extract. Methods: The endometrial tissue was autografted to Rat's small intestine. Rats with surgically induced endometriosis were orally and rectally administerd with Pinelliae Tuber extract for 40 days. Size of ectopic uterine implants at the serosal wall and concentration of progesterone, estradiol, $TNF-{\alpha}$ and IL-2, IL-4, IL-6, IL-I0 in serum were examined and compared with the control group. Results: There was no difference in the size of ectopic uterine implants of experimental group compared with control group. The concentration of IL-10 level was significantly decreased in orally administered experimental group and the concentration of progesterone, IL-6 level was significantly decreased in rectally administered experimental group. There was no significant difference between orally and rectally administerd with Pinelliae Tuber. Conclusion: Judging from the above results, it can be suggested that Pinelliae Tuber should be not a useful agent for inhibiting the proliferation of uterine endometrial tissue. There is no difference between orally and rectally administerd with Pinelliae Tuber extract.

Purpose : Astragalus membranaceus is a herb which has effectiveness of energy increase, protection against pathogenic and organ immune response control. Endometriosis has been thought to be related with immune response in uterus. Therefore in this study, the effects of Astragalus membranaceus on endometriosis were investigated. Methods : The endometrial tissue was autografted to rat's small intestine. Rats with surgically induced endometriosis was administerd with Astragalus membranaceus extracts for 40 days orally or rectally. We observed the size of ectopic uterine implants at the mesenteric with the naked eye and examined the concentrations of estradiol, progesterone, $TNF-{\alpha}$ and IL-2, IL-4, IL-6 and IL-10 in serum. Also, we inquired out the efficiency between oral and rectal administration groups. Results : The size of ectopic uterine implants of oral and rectal treated groups were much smaller than those of control groups. The concentration of estradiol, progesterone. $TNF-{\alpha}$ and IL-2 were significantly decreased in oral administration experimental group compared with the control group. The concentration of progesterone were significantly decreased in rectal administration experimental group compared with the control group. The efficiency of oral administration group was better than that of rectal administration group in the serum concentration of estradiol, $TNF-{\alpha}$ and IL-2. Conclusion : Our data suggest that Astragalus membranaceus reduce the size of ectopic uterine implants at the mesenteric wall and inhibit the growth of ectopic uterine implants. Judging from the above results, it can be suggested that Astragalus membranaceus should be a useful agent for inhibiting the proliferation of uterine endometrial tissue. May be, oral administration of Astragalus membranaceus is more effective than rectal administration for inhibiting the proliferation of endometriosis.

A 2-year-old female mongrel dog was referred to the Veterinary Medical Center of Chungbuk National University due to anorexia, depression and weight loss after the administration of exogenous estrogen for contraception in the local hospital. Although the dog was medicated with antibiotics and fluid for two weeks in the local hospital, there was a deterioration in the patient's general condition. Therefore the dog was referred to our Veterinary Medical Center. Hematological and biochemical analysis showed non-regenerative anemia, thrombocytopenia, severely immature leukocytosis, hyperbilirubinemia, hyperglycemia and elevated serum alkaline phosphatase, gamma-glutamyltransferase, and lactate dehydrogenase. Abdominal ultrasonography showed double line of gallbladder and irregular hypertrophic wall of uterus. On the basis of these examination's results and history taking, final diagnosis was exogenous estrogen-induced myelotoxicosis with cholecystitis and endometritis. The symptomatic therapy for estrogen toxicosis was performed for 26 days after the final diagnosis. However, the symptom had no response to therapy except endometritis and anemia. On day 135 after administration of estrogen, platelet and neutrophil count were normalized, but monocytic leukocytosis was occurred.

This study was desinged to investigate the effect of estrogen(Est) on the proliferating of progesterone(Prog) target cells. The spayed 13 rats(Wistar, approximately 300gm) were randomly alloted into 3 groups. One group was the control group and another Prog-treated group was injected with 1mg of Prog/rat/day for 2 consecutive days, and Estand Prog-treated group was injected intramuscularly with $17{\beta}$-estradiol $20{\mu}g/rat/day$ for 3 consecutive days and then with Prog for 2 days as above from 4th day. Rats were administrated intraperitoneally with bromodeoxyuridinc(Brdur,0.2mg/BW once) befero 2 hours of exanguination. In gross finding, the groups with more level of dimension and weight on the uterus were ordered as Est- and Prog-treated group, Prog-treated group and control group. The investigation by immunohistochemical methods using paraffin sections of the uteri was performed by using anti-Brdur antibody for labeling proliferating cells of Prog target cells. The groups with higher labeling index(LI) were ordered as Prog-treated grop, Est- and Prog- treated group and control group. The number of proliferating cells from Prog target cells in the rats were rather deceased by Prog injection following Est injection than prog injection only. The cell types with higher LI in the wall layers of all 3 groups were ordered as endometrial stromal cells, glandular epithelial cells, luminal epithelial cells, myometrial muscle cells and serosa methodelial cells, and the region with highest LI was functional zone of the endometrium and the region with lower LI was muscular layer and then those with lowest LI was serosa and also the considerable different LI from individual rat were observed.

Cynanchum wilfordii and Phlomis umbrosa Turcz. are known to contain isoflavone, a representative phytoestrogen. This study was performed to determine whether the extract mixture of C. wilfordii and P. umbrosa Turcz. would induce an estrogenic effect in ovariectomized rats. The extracts were administered to the ovariectomized rats at 30, 60, 120 mg/kg per day for 4 weeks, respectively. They showed no estrogenic effect, which was indicated by the decrease in uterus wall thickness as well as the increase in body weight and the level of cholesterol and triglyceride. The extracts also had no effect on the concentrations of estrogen and growth hormone in the serum. However, the increase in alkaline phosphatase activity, which leads to protection against the bone loss caused by ovariectomy, was noted on administration of the extract. Therefore, it seemed that the extracts of C. wilfordii and P. umbrosa Turcz. had no estrogenic effect in rats.

The purpose of this study was attempted to investigate the number changes of the growing and mature follicles in ovary following repeats of pregnant mare serum gonadotropin(PMSG) treatments for superovulation in nulliparous rats. Thirty two rats(Sprague-Dawely, about 200~250 gm) were randomized into 4 groups. Control group rats were sacrified at estrus phase confirmed by vaginal smear. PMSG-treated group 1 rats, PMSG-treated group 2 rats and PMSG-treated group 3 rats were sacrified at 48 hrs after injection once with PMSG 25 IU, after 2 repeated injection by a week interval, and 3 repeated injection, respectively. The uteri and ovaries of rats were removed and weighed and then were observed grossly and serial sections of all ovaries and some sections of uteri by paraffin embedding were stained with H-E. Number of ovarian follicles about 3 grades of small, middle and large follicles from seondary and follicles were investigated by LM photographies of ovary preparations. The criteria of the small, middle, and large follicles were based as small follicle with preantral follicles with 2~4 layers of granulosa cells surrounding the oocyte, as secondary follicles with more than 5 layers of granulosa cells and early signs of antral cavity or with small clefts on either side of the oocytes, and as tirtiary follicles with a single medium sized antral cavity or large well-formed antral cavity, respectively. In gross findings, the wall of the uteri in control group were thin, and those in 3 PMS-treated group were markedly thickened and some uterine lumen of those filled with fluid. In histological findings, the walls of the uteri from 3 PMSG-treated groups were hypertrophied and their blood and lymph vessels were dilated than those of control group. The ovaries fo 3 PMSG-treated groups were more increased in size and the cortexes were more developed and increased in width but there are no difference of development and changes in 3 PMSG-treated groups. The weight of the uteri and ovaries per rat in PMSG -treated group 1, 2 and 3 were a, pp.ared to be significantly increased 171.4$\pm$47.6%, 162.3$\pm$43.9%, 206.9$\pm$30.4%, respectively than those of control groups. The mean number of follicle per ovary in control group were a, pp.ared to be 17.1$\pm$3.5, 46.2$\pm$14.5, and 74.3$\pm$22.7 at large, middle and small follicles, respectively and total number of these 3 grade follicles per ovary were a, pp.ared to be 137.7$\pm$31.7. The mean number of follicle per ovary in PMSG-treated group 1 were a, pp.ared to be 25.6$\pm$7.3, 78.1$\pm$29.9, and 83.2$\pm$34.0, at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 187.5$\pm$58.8. The mean number of follicle per ovary in PMS-treated group 2 were a, pp.ared to be 21.9$\pm$5.2, 67.8$\pm$16.8, and 68.0$\pm$14.9 at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 157.7$\pm$26.2. The mean number of follicle per ovary in PMS-treated group 3 were a, pp.ared to be 21.7$\pm$4.8, 61.5$\pm$17.0, and 59.7$\pm$16.2 at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 143.5$\pm$29.6. The number of follicles in PMSG-treated group 1 a, pp.ared to be more number than other 2 PMSG-treated gruops and tended to be decreased by frequency of PMSG-treatment.

A survey of the internal parasites in 115 fishes of Ophicephalus argus was carried out in Kyungpook province during the period from January 1995 to November 1997. A species of trematode from the stomach and a species of nematode from the caeca of the fishes was discovered respectively. The trematode was identified as Azygia hwangtsinyi (Tsin, 1993) and the nematode as Pingus sinensis ($Hs\ddot{u}$, 1993). The fluke was pressed at thick of 0.1mm~0.2mm between slide glasses and fixed in 70% ethyl alcohol solution. The fluke was washed with tap water after fixation and stained with hematoxylin-carmin and mounted in balsam through routine methods. The nematode was fixed in 5% formalin solution and mounted with lactophnol or glycerine jelly. Morphology : Arygia hwantsinyi ; The fluke is elongate body with approximately parallel margins and rounded extremities in pressed preparations(Fig 1). The cuticle is unarmed. The oral sucker is ventro-subterminal in position. The ventral sucker is slightly smaller than oral sucker and positioned at 14.2% of body length from the oral sucker. The cirrus sac and genital pore is in mid-ventral line, slightly anterior to the ventral sucker. The oral sucker is succeeded by a well developed muscular pharynx. It is succeeded by a short inverted Y-shaped oesophagus. The inner wall of oesophagus is consisted of many fine folded membrane. The fine tubes of esophagus pass into the intestinal heads which are distended and presented a marked borderline between the fine tube and intestinal heads. The Intestinal heads start at level of pharynx and pass caudad in a zigzag course to end quite near caudal margin. The uterine coils occupy the intercecal area between the level of the cephalic margin of the ovary and about the level of the ventral sucker. The uterus is filled with many eggs. The testes are round or oval and placed one behind the other generally a little diagonally. The posterior testis is placed at level of 75.1% of body length. The ovary is oval, placed ahead the anterior testis. The shell gland not discernible outline is contacted with ovary ahead it. The vitelline glands are consisted of small oval vesicles. The vesicles occupy extracecal regions and between a little posterior of the ventral sucker and near caudal margin. Pingus sinensis : Female ; The cuticle is smooth and the cervical alae are well developed. The mouth opening is small, triangular, and without lips. The anterior end bears four sub-medial papillae. The oesophagus is divided into a muscular and glandular portion. The nerve ring is situated just at the junction of the muscular and glandular portions of the oesophagus. The vulva which has a prominent flap, is placed behind the middle of the body about one-third of the length of the worm from the posterior extremity. The vagina is strongly muscularised and after running anteriorly about $68{\mu}$, divides itself into two broad uterine tubes with an anterior and a posterior one. There are a few eggs in the uterine tubes. The tail is slender, straight and pointed. The ovary extends almost to the posterior extremity. Male : Male is smaller than female. The tail is pointed, curved and carrying well-developed caudal alae. A prominent muscular precloacal sucker is characteristic. The spicules are equal and short. There are four pairs of pedunculated pre-anal papillae, of which the most anterior pair are situated just at the level anterior to the muscular sucker. Two pairs of pedunculated papillae are present before the anus. There are five pairs of post-anal papillae of which the most anterior pair and the second counted from the posterior end are ventral and more marked than the ones which are situated laterally.

This study was designed to investigate the number of the growing and mature follicles following gonadotrophin treatments for superovulation in mature rats. Eighteen mature rats (Sprague-Duwely, initially 190~230gm) were randomly alloted into 3 groups. One group was control group, another FSH-treated group was injected intramuscularly with 0.5 units of follicular stimulating hormone (FSH) / rat, and third PMS and HCG-treated group was intramuscularly injected with 20~25IU of pregnant mare serum (PMS) / rat and then at the 48 hrs later, with 20~25IU of human chorionic gonadotrophin (HCG) / rat. The uteri and ovaries of rats were collected and then were observed grossly and serial sections of paraffin embedding ovaries were stained with H-E. Number of ovarian follicles by following 3 grades of large, middle and small follicles from secondary and tertiary follicles were investigated by LM photography of preparations. Small follicles were classified as secondary follicles of preantral follicles with more than 2 layers of granulosa cells surrounding the oocyte and middle follicles were classified as secondary follicles with early signs of antral cavity or with more than one small cavity on either side of the oocytes and large follicles were classified as tertiary follicles with a single medium sized antral cavity or large well-formed antral cavity. In gross findings, the uteri were slightly swelling in FSH-treated group and markedly swelling or filled with fluid in the uterine lumen in PMS and HCG-treated group. In histological findings, the shape and size of the follicles were diverse in middle and large follicles of FSH-treated group and PMS and HCG-treated group, and proportion of atretic follicles was increased in FSH-treated group and PMS and HCG-treated group than those in control group. The uteri of FSH-treated group and PMS and HCG-treated group were hypertropied or filled with fluid in the lumens and walls of uteri. The wall tissue layers were flattened and their blood and lymph vessels were dilated. The mean number of follicle per ovary in control group were appeared to be $17.1{\pm}5.6$($14.0%{\pm}4.6%$), $37.8{\pm}9.1$($30.9{\pm}7.4%$) and $67.6{\pm}30.1$($55.2{\pm}24.6%$) respectively at large, middle and small follicles and total number of these 3 grade follicles were appeared to be $122.5{\pm}40.0$. The mean number of follicle per ovary in FSH-treated group were appeared to be $22.8{\pm}7.0$($17.4%{\pm}5.3%$), $43.4{\pm}6.6$($33.2{\pm}5.1%$) and $64.5{\pm}13.0$($49.3{\pm}9.9%$) respectively at large, middle and small follicles and total number of these 3 grade follicles were appeared to be $130.7{\pm}16.6$. The mean number of follicle per ovary in PMS and HCG-treated group were appeared to be $29.7{\pm}11.0$($16.3%{\pm}6.0%$), $61.9{\pm}17.2$($33.9{\pm}9.4%$) and $91.1{\pm}28.2$($49.9{\pm}15.4%$) respectively at large, middle and small follicles and total number of these 3 grade follicles were appeared to be $182.6{\pm}32.7$. The above findings reveal that large follicles were increased 29.8% in FSH-treated group and 73.7% in PMS and HCG-treated group than those in control group and in histologic findings, proportion of atretic follicles were more increased in ovaries with more number of more developing follicles.
