RESUMEN
Ovarian Pregnancy is an uncommon type of ectopic pregnancy , the cause of which is unknown , The use of the intrauterine device (IUD) has been claimed to increase the incidence of ovarian pregnancy. Because of its rarity the diagnosis is usually only made at laparotomy. A case of primary ovarian pregnancy in a patient with an intrauterine device (IUD) is reported.

Background: Cholangiocarcinoma, the cancer of biliary epithelium, is highly prevalent in Northeast Thailand and is associated with the liver fluke, Opisthorchis viverrini, infection and the consumption of carcinogen contaminated daily food. Diagnosis of this cancer is practically based on clinical and utrasonography. However, several markers can be used in conjunction with the standard procedure to increase diagnosis accuracy including biliary cytology as described in carcinoma of other pancreatobiliary diseases. On the basis of cancer cells can be exfoliated into the bile and they can be detected by routine Papanicolaou staining. In endemic areas of cholangiocarcinoma and opisthorchiasis, there is no report about biliary cytology and percentage of positive malignant cells presented in the bile, here we examined biliary cytology of the gallbladder and/or hepatic bile to clarify its usefulness potential for using in diagnosis.Objective: To study biliary cytology and examine Opisthorchis-ova in the gallbladder/hepatic bile in patients with cholangiocarcinoma in Northeast Thailand.Patients and Methods: Aspirated gallbladder and/or hepatic bile from 100 histological proven cholangiocarcinoma cases who admitted to Srinagarind Hospital during December 1996 to July 1998 were studied. Four Papanicolaou\’s stained smears per bile sample per case were examined for the presence of malignant or atypical cells and O. viverrini ova. Positive specimens for malignancy contained singly, numerous malignant cells and/or in three dimensional clusters. Liver fluke positive cases contained ova with distinct bilaminar walls and prominent shoulder.Results: Overall, the positivity for malignant cells and O. viverrini ova was 51 % (51/100) and 27 % (27/100), respectively. Five cases were suspicious for malignancy. Paired gallbladder and hepatic bile specimens were obtained in 32 cases. Of these, the positivity for cancer cells was significantly higher in the hepatic bile than in the gallbladder bile (2-test, p\<.01). Five cases with gallstone were negative for malignant cells.Conclusion: The results indicate that cancer cells are frequently detected in the bile, particularly in hepatic bile from patients with cholangiocarcinoma. This study implicates the potential application of biliary cytology in diagnosis of this cancer, i.e. in the bile from ERCP or duodenal drainage which is less invasive, in conjunction with other investigations in endemic areas.

RESUMEN
Background: Diabetes is a condition which is known to be associated with a variety of connective tissue abnormalities which contribute to impaired wound healing, leading to the chronic ulcer formation. Centella asiatica Linn. and Garcinia mangostana Linn. are widely used as Thai traditional medicine including wound treatment. However, the effects of both plant extracts in diabetic condition had not been experimented.Objective: To study the effects of topical administration of Centella asiatica Linn. and Garcinia mangostana Linn. on diabetic wound.Materials and Methods: Male Spraque-Dawley rats (64 rats) were divided into 2 groups: Normal control and diabetes induced groups, each group was divided into 4 groups. The wounds were and treated by placebo, Centella asiatica Linn., Garcinia mangostana Linn. and neomycin.Results: It was shown that the wounds of the treated group epithelialized faster and the wound contraction rate was higher than the non-treated groups.Conclusion: The present study results confirmed the folkloric utilization and suggested the beneficial effects of both plant extracts for treating diabetic wounds in human being. However, the further studies with purified constituents were required to understand the complete mechanism of wound healing promotion induced by both Centella asiatica Linn. and Garcinia mangostana Linn.Key words: wound healing, diabetes, Centella asiatica Linn., Garcinia mangostana Linn.
