  • 전기영동에 의하여 진도개와 삽사리의 혈청 단백질을 분석하였다. 이들의 혈청 단백질 전기영동상은 5개의 분획으로 나눌 수 있었다. 진도개의 총 혈청단백질은 8.40$\pm$1.63(g/dl)이었으며 albumin과 globulin의 비(A/G)는 0.81 $\pm$ 0.25이었다. 삽사리의 총 혈청단백질은 8.23 $\pm$2.20(g/dl)이었고 A/G는 0.78 $\pm$ 0.23이었다. 연령에 따라 Y-globulin의 양이 가장 크게 변했으며 진도개와 삽사리의 albumin과 globulin의 비는 다른 품종의 개들보다 낮았다.

  • Osteoporosis is a bone disease associated with reduced bone mineral density resulting in debilitating bone fractures. The present study was carried out to determine the influence of ovariectomy(OVX) on serum level of sex steroid and bone metabolism, as well as bone mechanical property, in OVX subjects in comparison with controls. Body weight and food intake was significantly increased in OVX subjects than in controls. The serum level of estradiol(E2) was significantly lower in OVX subjects than in controls. The serum level of calcium and alkalin phosphatae were significantly increased in OVX subjects than in controls. The bone strength, based on the three point bending test, was not significantly different. Seven weeks after ovariectomy, the cavities in the bone reached 223% of the normal. In conclusion, seven weeks after ovariectomy osteoporo sis was evidently appeared.

  • Inorganic phosphate (Pi) in rabbit plasma was found to block completely phosphotyrosine phosphatase (PTPase) activity without affecting the alkaline phosphatase (ALPase) activity. Our results provided that (1) PTPase activity and inhibitor are separated after G-25 gel-filtration. (2) This inhibitor is heat stable and trypsin-resistant and it can be removed by dialysis using 3 Kd cut-off tubing. (3) The elution pattern of the inhibitor is identical to that of Pi, and by performing a seperate run with inorganic phosphate. (4) The PTPase activity was recovered following an incubation with $CaCl_2$ (10 mM).

  • To define the risk facots of subclinical vitamin D deficiency in postmenopausal women, circulating serum 25-hydroxyvitamin D levels, known to be the indicator of vitamin D status, were measured and risk faxtors affecting it were investigated in 27 women with low 25-hydoxyvitamin d level(ie, the study group : serum 25-hydroxyvitamin D<10ng/ml) by comparing to 55 age-matched control(the control group) were analyzed. The serum level of 25-hydorxyvitamin D was analyzed by HPLC(High Pressure Liquid Chor-matography) and analyzed biochemical parameter. The following information was obtained by interviews : sociodemographic charateristics, the intake of food containing vitamin D, proxy measure of sunlight exposure(time spent outdoors), and reprocuctive histpry of the subjects. The study group had significantly lower levels of serum calcium, increased levels of iPTH and alkaline phosphatase, Among the dietary determents, energy, protein, fat, calcium, phophorus, and vitamin D intakes were lower in the study group than the normal group. The time spent outdoors in a day was not significantly different between the two groups. However, during the day, a specific time of time spent out doors between 12:00 and 14:00 was significantly lower in the study group. Logistic analysis revealed that vitamin D and calcium intake were more important affecting factors than the time spent outdoors in post menopausal women.

  • 무 유식물에서 acid phosphatase의 활성은 산성인 pH 5.5에서 최대치를 보였다. 0.5 mM ABA처리로 acid phosphatase의 활성이 대조구보다는 오래 지속되였고, 0.5 mM NaCl 처리시 도 acid phosphatase 활성의 변화는 ABA 처리 때와 유사하였다. 그러나 저온처리를 하면, 대조구에 비해서 효소의 활성이 급속히 감소되었다가, 대조구의 acid phosphatase는 거의 같은 활성을 유지하는 동안 처리구의 acid phosphatae의 활성은 6 일까지 서서히 증가되었다. Acid phosphatase는 저온처리, ABA와 NaCl처리에 대항하여 식물이 스트레스에 대처하도록 생화학적인 반응에 관하는 것으로 보인다.

  • cis-Dichlorodiammineplatinum (II) (cis-Platin), a metallic compound, has widely been used as an effective anticancer chemotherapeutic agent. The precise mechanism of action of this agent is still unknown, but it is postulated that cis-Platin may act on the cancer cell like bifunctional alkylating agents. Although this agent is very beneficial to the patients with cervical cancer, germinoma of testis, neuroblastoma and others, it may also damage to the normal cell so that many side effects; severe hemorrhagic enterocolitis, bone marrow depression, renal damage and liver damage will develope. This experiment has been undertaken to pursue the cytotoxic effects of the cis-Platin on the ultrastructures of the interalveolar septum in the mouse lung. A total of 55 healthy male mice of ICR strain were used as experimental animals and divided into 5 mice of normal control group and 50 mice of cis-Platin treated group. The mice of cis-Platin treated group were sacrificed by carotid exsanguination at 6, 12, 24 hours, 3 days and 7 days after intraperitoneal injection of 6.0 mg of cis-Platin ($Abiplatin^R$ Abic Co. Ltd.) per kg of mouse body weight. The specimen obtained from the lower lobe of left lung were sliced into $1mm^3$ and prefixed with 2% glutaraldehyde -2.5% paraformaldehyde solution prepared with Millonig's phosphatae buffer solution (pH 7.4) at $4^{\circ}C$ for 3-4 hours. After postfixation with 1% osmium tetroxide solution all specimens were embedded in Epon 812. Ultrathin sections about $600-800{\AA}$ in thickness were stained with uranyl acetate and lead citrate and observed with Hitachi-600 electron microscope. The results obtained were as follows: 1. Local swellings with increase of electron density and number of pinocytic vesicles in the cytoplasms of the type I pneumocyte and endothelial cell of the blood air barrier in interalveolar septum of cis-platin treated mice were observed. 2. Cisternae of rough endoplasmic reticulum were dilated and sacculated in association with detachment of membrane bound ribosomes of the type II pneumocyte in interalveolar septum of cis-Platin treated mice. 3. Swollon mitochondria with uneven electron density of their matrix were observed in the type II pneumocyte of interalveolar septum in the cis-Platin treated mice. 4. The lamellae of lammelar bodies in type II pneumocyte of interalveolar septum in cis-Platin treated mice were devoided or transformed into homogeneous electron dense material. It is consequently suggested that cis-Platin would induce the cellular edema of type I pneumocyte and endothelial cell, and degenerative changes of cytoplasmic organelles of the type II pneumocyte in the interalveolar septum of the mouse lung.
