The relationship between vaginal mucous electric resistance and plasma progesterone concentration for optimal mating time in Beagle bitches / 동물의과학연구지

The objective of this experiment was to assess the relationship between electrical resistance of the vaginal mucosa and plasma progesterone for optimal mating time in the bitch. Eight mature beagle bitches were examined, and we observed eight times of estrus. Vaginal electric resistance was recorded weekly using a Draminski ovulation detector in anestrus, and daily in estrus. Plasma progesterone concentration was estimated by radioimmunoassay. In the bitch, incline in vaginal electric resistance (376.20 +/- 105.63 units) showed a closely association with the onset of proestrus. Ovulation day was determined as the first day when plasma progesterone concentration increased above 5.0 ng/ml (Day 0). On Day 0, vaginal mucous electric resistance was 438 +/- 132 units. Vaginal mucous electric resistance showed a slight decrease or was maintained until Day 0. However, it showed an explosive increase, and peaked on Day 1~3, which was above 600 units. Two of eight cases peaked on Day 1, three of eight cases were revealed on Day 2, and others were revealed on Day 3. After Day 4, resistance showed a rapid drop to below 600 units and reached 200 units on Day 8. The optimal mating time was determined when vaginal mucous electric resistance was above 600 units.

A Case Of Rheumatoid Arthritis Accompanied By Severe Eosinophilia / 대한류마티스학회지

Eosinophilia is usually accompanied by parasite infestation, allergic condition, drug, collagen disease, and idiopathic hypereosinophilic syndrome. In about 10 to 40% of rheumatoid arthritis patients, peripheral blood reveals eosinophilia. Of the rheumatic disease, eosinophilia may occur in rheumatoid arthritis, sarcoidosis, polyarteritis nodosa and other vascultis. Patient with eosinophilia must be carefully followed up due to possibility of progression to eosinophilic leukemia or myeloproliferatire disease. We experienced a case of rheumatoid arthritis with severe eosinophilia for a period of more than one year in a 53 year-old female patient, eosinophil more than 85% in the peripheral blood, but in spite of careful laboratory study, there was no evidence of parasite infestation, allergic disease and malignant condition that may cause eosinophilia. Therefore we concluded that her severe eosinophilia was associated with rheumatoid arthritis itself, and now she is intensively followed up at the outpatient department. We have to look for any malignant transformation during her clinical course. Marked eosinophilia associated with rheumatoid arthritis is very rare, so we report this case with a review of literatures.

A Clinical Study on the Antihypertensive Effect of Fosinopril

BACKGROUND: Fosinopril is a new phosphorous containing angiotensin converting enzyme inhibitor. To assess the antihypertensive efficacy and safety of fosinopril, the clinical trial was done in patients with mild to moderate hypertension. METHODS: In 30 patients with mild to moderate essential hypertension, we administered fosinopril 10-20mg once daily for 10 weeks and checked their blood pressure every 2 weeks. RESULTS: The blood pressure decreased from 158+/-12.3/103.4+/-4.2mmHg to 139+/-7.5/88.4+/-5.9mmHg at the end of treatment(p<0.05). Heart rate did not change significantly during therapeutic period. Of 30 patients, the efficacy of fosinopril therapy disclosed 25 patients(83.7%) with normal diastolic pressure of more than 10mmHg decline of diastolic blood pressure. But two patients had no effects and three patients were not followed up. The adverse reactions due to fosinopril were reported in 3 patients(10%) with dry cough, 2 patients with palpitation(6.7%) and 1 patient with weakness(3.3%), but there were no patients who discontinued fosinopril due to adverse effect. CONCLUSION: Fosinopril has an excellent antihypertensive effect at low dosage as a first line antihypertensive agent or as a substituting agent for other antihypertensives in patients with mild to moderate essential hypertension.
