The ovarian follicular fluid was found to contain steroidogenesis stimulatory protein similar to albumin from human and buffalo. Therefore, the albumins from various species, commercial and purified, were studied for their steroidogenic effect on progesterone secretion by granulosa cells from buffalo ovaries, during culture. A dose of $20{\mu}g$ of bovine serum albumin was optimum to exhibit maximum progesterone secretion on day 6 of culture, in medium ($350{\mu}l$) containing $10^5$ cells. Among commercial albumins, chicken albumin showed highest effect on progesterone secretion, which was followed by albumins from goat, bovine, human, sheep and rat, respectively at day 6 of culture. The albumins were also purified from blood serum of buffalo, goat and rat using salt fractionation, ion-exchange chromatography, gel filtration and SDS-PAGE. The highest stimulatory effect on progesterone secretion was shown by albumin purified from buffalo blood serum and lowest by that from rat blood. Comparatively the buffalo and goat albumins were more biologically active than commercial albumins. The presence of some active molecules conjugated with freshly purified albumins may be responsible for better stimulatory effect.

1. Amino acid compositions were determined by amino acid analyzer. Through the analysis of these samples, it was found that glutamic acid was the most abundant; glycine, aspartic acid, lysine and threonine were rich; and tryptophan and methionine were the limiting amino acid. 2. Albumins, globulins, gliadins and glutelins were extracted from the Kangwon hull, Kangwon rice buckwheat, and wheat. The relative proportions of protein fractions were 52.45 : 10.14 : 16.61 : 20.80% in Kangwon hull buckwheat, 21.10 : 13.80 : 28.40 : 36.70% in Kangwon rice buckwheat and 6.87 : 1.65 : 42.85 : 48.6% in wheat, in the order of albumins, globulins, gliadins and glutelins. 3. Polyacrylamide gel electrophoresis (PAGE) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) were performed to identify the subfractions of each protein fraction. The electrophoregrams of PAGE showed that the same fractions of both Kangwon hull buckwheat protein and Kangwon rice buckwheat protein had very similar electrophoretic patterns to each other respectively, but there were significant differences in the patterns between buckwheat proteins and wheat proteins.

The possibility of using a fluorescence probe technique for the study of ibuprofenlysine binding to human and bovine serum albumin was investigated. 1-anilino-8-naphalenesulfonate was used as the probe. The number of binding sites of human and bovine serum albumins for ibuprofenlysine appears to be 4 and 2, respectively. By using this technique, the association constants were found to be $1.533{\times}10^{4}M^{-1}$ and $2.238{\times}10^{4}M^{-1}$, respectively.

유혈목이(Rhabdophis tigrimus)의 혈장알부민을 polythylene glycol과 ethanol 침전 방법에 의해 정제하였고 혈색소는 agar-gel 전기영동방법에 의해 정제하였다. 이 두 단백질과 유혈목이 혈장을 각각 토끼에 주사하여 항혈청들을 얻었으며 포유류 1종, 조류 1종, 파충류 9종, 및 양서류 1종의 혈장 및 혈구파쇄물과 면역확산 및 면역 전기영동을 실시하였다. 혈장알부민과 혈장에 대한 항혈청들은 유혈목이 혈장알부민과만 반응을 나타냈고 다른종의 혈장알부민과는 반응을 나타내지 않았다. 혈색소에 대한 항혈청은 8종의 사류 혈색소와 강한 반응을 나타냈다. 파충류의 혈장알부민의 구조는 상당히 빠르게 변형되어져 왔고 파충류의 경우 혈색소 분자는 강한 구조상의 상동성을 갖고 있는 것 같다. 그러므로 파충류의 경우 혈색소 분자의 구조는 혈장알부민의 구조보다 느리게 변형되어져 온 것으로 생각된다.

네가지 쌀단백군의 양적 관계는 주로 추출조건에 의하여 좌우되며 albumin 및 globulin의 추출양은 교반방법보다 추출온도에 의하여, glutelin은 사용용매의 종류와 pH에 의하여 추출양이 크게 좌우되었다. 적합한 쌀단백질의 추출로는 albumin 및 globulin은 0.5M-NaCl용액으로 $0{\sim}5^{\circ}C$에서, prolamin은 70%(v/v) ethanol용액으로 상온에서, glutelin은 0.1N acetic acid보다는 0.5% SDS-borate buffer (pH 8.3) 과 0.6% ${\beta}-mercaptoethanol$을 포함한 동일용액을 사용하는 것이 효과적이었다. 상기방법으로 추출한 각 단백군 구성성분의 분자량 분포는 albumin은 29,000, $18,000{\sim}15,000$ 및 12,000의 세가지이며 globulin은 27,000, 21,000 17,000 및 12,000의 4가지 이외에 고분자량의 단백질($10^5$이상)로 되어 있고 prolamin은 16,000, 0.5% SDS-borate buffer에 가용성인 glutelin은 35,000, 21,000, 17,000 및 15,000의 4가지와 이외에 globulin의 경우와 같이 고분자 단백질로 구성되어 있었다. Prolamin을 제외한 세 단백군은 각각 disulfide bond로 연결된 subunit를 가지고 있는 구성성분을 포함하고 있음을 알 수 있었다. SDS-glutelin은 Sephadex G-150 column chromatography에 의하여 세가지 fraction으로 분리할 수 있었다. Albumin과 globulin은 starch gel 전기영동상 산성 (pH 3.1)에서는 총 13개 및 21개의 band를 각각 나타내었고 염기성 (pH 8.95)에서는 총 4개 및 6개의 band를 확인할 수 있었다. 쌀품종들은 albumin과 globulin의 starch gel전기영동 pattern에 의하여 구별할 수 있었다. 산성조건에서는 특수 band의 존재 또는 band의 조합양상에 의하여 각 품종의 구별이 가능하였고 염기성조건에서는 각 품종별 구별은 할 수 없었으나 Japonica종을 Indica 또는 Japonica와 Indica교배종과 분리 식별할 수 있었다.

To isolate antifungal substances from Korean radish (Raphanus Sativus L.) seeds, various purification techniques such as DE52 cellulose anion exchange, SP-Sephadex C-25 cation exchange, and Sephadex G-50 gel filtration chromatographies were used. The molecular masses of two purified R. sativus antifungal proteins (RAPs) were estimated to be about 6.1 kDa (RAP-1) and 6.2 kDa (RAP-2) by SDS-PAGE, and 5.8 kDa(RAP-1) and 6.2 kDa (RAP-2 by a gel filtration chromatography, respectively. Purified proteins RAP-1 and 2 clearly exhibited different growth inhibitory activities against other microorganisms like Candida albicans and Saccharomyces cerevisiae. Although they have similar molecular masses, both RAP-1 and 2 proteins are not identical because their microbial inhibitory actions were different. Therefore, RAP-1 could be a new antifungal protein when compared with the antifungal activities of 2S albumins, Rs-AFPs, Mj-AMPs, chitinase, glucanase, permatin, and ribosome inactivating proteins, all of which are anifungal proteins of plants.

This study was performed to assess clinical signs, sedative effect and clinicschemical profile of a mixture of fentanyl-azapemne-xylazine(Fentazine$^{(R)}$) in formed elk Twelve male elk(Cervus canadensis) were immobilized with Fentazine, and blood samples were taken of femoral venous blood. Samples were analyzed in the conditions of 10- and 30-minute after administration of the drug. Heart rates, respiratory rates, and body temperatures were in normal ranges during Fentazine anesthesia. After iqiection of Fentazine, most of elk were recumbency and did not respond to needle prick In young adult(3.5.4.5 years old) elk a high dose(>3.0 ml/head) of Fentazine does not result in more sedation, but it does prolong the duration of sedative effect. Fentazine induced sufficient analgesia far velvet antler removal and hoof trimming in elk Salivation, urination, intermittent apnea and mild bloat were observed in elk Globulin, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, calcium, magnesium and phosphorus values were in normal ranges for at least 30 minutes after Fentazine administration. Total protein, albumins cortisol and prothrombin values were slightly increased during sedation(p<0.05). It was concluded that Fentazine is effective analgesic drug being useful for velvet antler removal and hoof trimming.

Alcoholic extract of Terminalia arjuna [TA] was evaluated far its hepatoprotective activity against carbon tetrachloride (CCl$_4$)-induced hepatic damage in rats. The hepatoprotective activity of TA was evaluated by measuring levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (SALP). The serum levels of total proteins(TP), total albumins (TAL) and bilirubin (BILN) were also estimated. The histological studies were also carried out to support the above parameters. Silymarin (SM) was used as standard drug. Administration of TA (250 and 500 mg/kg/po) markedly prevented CCl$_4$-induced elevation of levels of SGOT, SGPT, SALP, TP, TAL and BILN. These biochemical observations were supplemented by histopathological examination of liver sections. Alcoholic extract of TA also shown significant in-vitro free radical scavenging activity against 1, 1-diphenyl-2-picryl hydrazyl (DPPH) and nitric oxide (NO) radicals. Thus, the present study provides a scientific rationale for the traditional use of this plant in the management of liver diseases.

Patients with nephrotic syndrome (NS) are generally known to be at greater risk for thrombosis, with arterial thrombosis-related complications being relatively rare compared to venous thrombosis-related complications. This report describes a 46-year-old male with historically proven minimal change disease (MCD) complicated by acute aortoiliac thrombosis. He had been diagnosed with MCD 8 months previously and was treated successfully with steroids. He was prescribed a second course of high-dose steroids (prednisolone 1 mg/kg/day) due to a relapse of MCD at the outpatient clinic 8 days before the emergency department visit. The patient presented with severe pain in both lower limbs and was diagnosed with aortoiliac thrombosis that developed during high-dose steroid treatment. He subsequently underwent surgical thromboembolectomy. Hypoalbuminemia has the strongest association with the risk of thromboembolism. According to international clinical practice guidelines, anticoagulant therapy is recommended when serum albumin is ≤2-2.5 g/dL. However, as serum albumin levels may be relatively high in the early phase of NS, as in this case report, an individualized anticoagulation strategy for each patient should be considered, regardless of serum albumin levels.
