This review gives a brief presentation of the types, structure, synthesis, and application of amorphoustransition metal borides (Mt-B) in particular the bulk or supported nickel and cobalt borides (NiB andCoB). Mt-B materials are amorphous metal-metalloid alloys and constitute an important group of catalyticsystems due to their special chemical and physical properties, including broad composition, structuralhomogeneity, and high concentration of coordination unsaturated sites. These features along withthe relatively cheap and simple methods of synthesis make them interesting alternative catalytic materialsfor numerous new, cost-effective, and environmentally sustainable yields and applications. Muchattention has been paid to Mt-B as an interesting alternative to the industrially applied catalysts basedon expensive and/or susceptible to sulphur poisoning, precious metals, and Raney nickel. Therefore, thisreview presents the application of Mt-B in different sectors: chemical production, energy storage/conversion,and environmental remediation. The current and future directions of research in this area areanalysed.

Spring black stem and leaf spot, caused by Phoma medicaginis, is an issue in annual Medicago species. Therefore, in this study, we analyzed the response to P. medicaginis infection in a collection of 46 lines of three annual Medicago species (M. truncatula, M. ciliaris, and M. polymorpha) showing different geographic distribution in Tunisia. The reaction in the host to the disease is explained by the effects based on plant species, lines nested within species, treatment, the interaction of species × treatment, and the interaction of lines nested within species × treatment. Medicago ciliaris was the least affected for aerial growth under infection. Furthermore, the largest variation within species was found for M. truncatula under both conditions. Principal component analysis and hierarchical classification showed that M. ciliaris lines formed a separate group under control treatment and P. medicaginis infection and they are the most vigorous in growth. These results indicate that M. ciliaris is the least susceptible in response to P. medicaginis infection among the three Medicago species investigated here, which can be used as a good candidate in crop rotation to reduce disease pressure in the field and as a source of P. medicaginis resistance for the improvement of forage legumes.

자궁근종에서 심한 복수를 동반한 경우는 외국문헌상 10만예만이 보고되어 있으나2), 국내에서는 아직 보고된 바 없다. 본 병원에서는 49세의 다산부에서 심한 복수 및 제대허니아를 동반한 6.520gm의 자궁근종을 경험하였기에 문헌고찰과 함께 보고하는 바이다. The reported cases of huge uteine myoma with umbilical hernia and massive ascites are extremely rare. This case, 49-year old multipara, was referred to our hospital due to distended abdomen and umbilical hernia. After removal of the uterine myoma, ascites had been completely disappeared. Pathologically, a leiomyoma of the uterus was confirmed.

Estrogen replacement therapy is known to reduce the incidence of cardiovascular disease and osteoporosis in postmenopausal women. Estrogen has beneficial effect on bone density and adding progesterone to estrogen is known to have synergistic effect. However, the effect of progesterone on bone mineral density had not been precisely evaluated in Korean postmenopausal women. To evaluate the impacts of progesterone on bone mineral density during estrogen replacement therapy, we conducted the randomized 2-year trials of conjugated equine estrogen (Premarin 0.625 mg/day) with or without cyclic progesterone(medroxyprogesterone acetate : MPA 10 mg/day for 12 days) in 105 postmenopausal women. Bone mineral density was measured in the lumbar vertebrae(L2-L4) using dual energy X-ray absorptiometry(DEXA) at the beginning of the treatment, 6 onths, 12 months and 24 months later, respectively. In Premarin only group, bone mineral density at 6 months and 12 months after treatment did not show significant difference from baseline value. But bone mineral density on 24 months after treatment showed significantly increased value(p value$lt;0.05) than that of initial. In Premarin plus MPA group, bone mineral density at 12 months and 24 months after treatment showed significantly increased than baseline(p value$lt;0.05). And compared with Premarin only group, Premarin plus MPA group showed significant increase in spinal bone density after 2 years treatment(p value$lt;0.05). These results suggest that the addition of MPA in estrogen replacement therapy appears to increase in bone mineral density more than unopposed estrogen. Thus combination of estrogen and progesterone appeared to be effective long-term prophylactic treatment regimen upon postmenopausal bone loss.

The study was carried out retrospectively based on the clinical chart of 1746 obstetrical patients who received X-ray pelvimetry among a total of 14,000 patients admitted to the Dept. Of Ob. & Gy. from Sept. 1, 1968 to dec. 31, 1975 except 1969. The Colcher-Sussman technique was used to measure the various diameters of the pelvis while the biparietal diameter and weights of fetus were obtained postpartum. Even though pelvimetry has been widely used over the years and has been generally accepted as a clinical tool, this study was mainly concerned with relationships between pelvic diameters and fetal weight-size factors. 1. 1436 X-ray pelvimetry were taken in patients thought to have dystocia with a vertex presenting. In these patients, 53.6% had vaginal delivery, 4.2% had a mid forceps delivery and the remaining 42.1% received a cesarean section. 2. In the same group, when the A-P of the inlet was less than 10.0cm, the Cesarean section rate was 70.2% when between 10.0cm and 10.4cm the rate was 47.0% and above 10.5cm the rate was 30.5%. 3. Even better correlation is found in terms of type of delivery when the A-P of the inlet is related to the biparietal diameter of the infant. When the difference was between 1.0cm and 1.4cm the Cesarean section rate was 52.8% when the difference was between 1.5cm and 1.9cm the Cesarean section rate was 24.4% and above 2.0cm the rate was 14%. with the birth weight above 3500gm and the difference under 1.4cm the Cesarean section rate was around 58%. 4. When the transverse diameter of midpelvis was between 8.5-8.9cm the Cesarean section rate was 77.1% The mid-pelvic transverse diameter was much less accurate in predicting the method of delivery especially Cesarean section and mid-forceps delivery. 5. When used with nulliparous breech presentation the section rate was 46%. 6. In 1746 case who taken X-ray pelvimetey, 413 cases were spontaneous premature rupture of membrane, and the subsequent section rate was 40.4%.
