This paper aims to prove the effects of Squalene (SQ) on the cellular toxicity of 5-FU to the mouse which pretreated with SQ and then treated with 5-FU. The results of the group A (treated with only 5-FU) are as follows. The nucleus was destroyed at 24 hours and 48 hours group, however, somewhat repaired at 72 hours group. The dilated inner cavity and the irregular lamellae of the rough surfaced endoplasmic reticulum (RER) were observed continually until 72 hours group. The inner cavity of the smooth surfaced endoplasmic reticulum (SER) were dilated in all groups. However, the destroyed and the normal membrane were observed simultaneously at 72 hours group. The inner membrane of the mitochondria were almost repaired at 96 hours group. The results of the group B (treated with 5-FU and squalene) are as follows. The nucleus was a little influenced by the toxicity of 5-FU at 24 hours and 48 hours, RER were observed to keep the typical lamella structure of cisternae from 24 to 72 hours group, but inner cavity kept on dilating. In SER, inner cavity were also observed to flatten from 24 to 72 hours group. Mitochnodria were always shown normal. All cell organelles were simillar to those of normal groups at 96 hours. Accordingly, it can be said that the treatment of 50 prevents the cytotoxicity of 5-FU on cell organelles of liver cell and that is concerned with the formation of membrane system of cell organelles.

김정상,최영복,김종세,Kim, Jeong-Sang,Choi, Young-Bok,Kim, Jong-Se 한국현미경학회 1997 Applied microscopy Vol.27 No.1

The objective of the present study was to investigate the cytotoxicity of adriamycin in liver cells (group A), and the protective effect of squalene to the hepatocytes to which adriamycin-induced cytotcxicity (group B) was examined by transmission electron micro-scope. In the group A, The cisternae of rough endoplasmic reitculum and smooth endoplasmic reticulum are dilated/disoriented at 24 hours and 48 hours. The inner and outer membrane of mitochondria are detached or destructed , and attached ribosomes of rough endoplasmic reticulum are diminished in number. The cisternae of the smooth endoplasmic reticulum are dilated, and the cristae of mitochondria are disrupted at 72 hours and 96 hours. In the group B, the cisternae of the rough endoplasmic reticulum and smooth endoplasmic resticulum are dilated at 24 hours. The cisternae of the smooth endoplasmic reticulum are dilated at 48 hours. The cell organelles of hepatocytes are recovered from cytotoxicity at 72 hours. These results suggest that 50 is not only concerned with composition of the membrane system of the cell organelles but also decreased the cytotoxicity of the hepatocytes.

본 실험은 화상을 입은 생쥐에서 SQ의 치유 효과를 알아보기 위함에 있다. 실험군은 7개군으로 구분하였다; 대조군, 화상군, 그리고 화상을 입헌 후 SQ를 처치한 군. 대조군을 제외한 모든 군은 등 부위에 2도 화상을 입혔다. SQ를 처치한 모든 군은 하루에 한 번씩 10초 간격으로 순수한 SQ 3방울을 도포하였다. 화상 후 10일 동안 조직학적 및 미세구조적 변화를 광학 현미경과 전자현미경으로 관찰하였다. 광학현미경으로 관찰한 결과, 화상군의 표피층의 모든 부분은 SQ를 처치한 군보다 더 심한 상처를 입었다. SQ를 처치한 6째와 10일째 군에서, 기저층은 분화가 활발하였고, 가시층의 각화세포는 수적으로 매우 증가하였다. 전자현미경으로 관찰한 결과, SQ를 처치한 모든 군의 기저층에서 세포분열이 화상군에서보다 더 활발하게 나타났다. 특히, SQ를 처치한 10일군에서는 이상적인 결과를 얻을 수 있었다; 대조군보다 더 두꺼운 가시층과 많은 각화세포, 뚜렷한 세포간교, 그리고 멜라닌세포를 포함하는 튼튼한 기저층. 이와 같은 결과로 보아 SQ은 표피성장인자(EGF)를 활성화시키고, 유해산소의 제거 역할을 하며, 막계에 에너지원을 제공할 가능성이 있다. 이 실험의 결과는 SQ가 화상 치료에 특수한 효과가 있다고 사료된다. The purpose of this experiment was to know the healing effects of saualene on the burned mouses. The experimental groups were divided into seven groups: the control group, the burned groups, and 50 treated groups after burned. All groups except the control group burned with second degree on a dorsoanterior part. All groups that treated with 50 adapted three drops of pure squalene at 10 seconds interval; one time a day. The histological and ultrastructural changes during 10 days after burned were observed by light and electron microscope. Under the light microscope, all parts of epidermal layer of the burned groups were wounded deeper than the 50 treated groups. At 6 and 10 days groups with 50 treated, especially 10 days, the basal layer was greatly differentiated, and the prickle cells in the spinous layer were greatly increased in number. Under the electron microscope, the cell divisions of basal layer in all groups that treated with 50 were more activated and rapidly regenerated than the all burned groups. Especially, some fantastic results obtained from the 10 days group with SQ treated; much thicker spinous layer than the control group, many prickle cells, fine intercellular bridges, and healthy basal layer contained melanocytes. These results suggest that squalene may active the epidermis growth factor (EGF), acts as scavenger, and provide sources of energy in the membrane system. The results of this experiment consider that squalene has specific effects for burn healing and regeneration.

Generally speaking, the basic law of government or the constitution manifests political, economic and social and cultural identities of a nation-state and is put on a higher plane than any law in the legal system. Thus, an analysis of it is the first step towards understanding political, economic and social and cultural identities, as well as the aspects of people’s lives, of a nation-state. Religious and secular identities are both in harmony and tension with each other in the basic law of government (or the constitution) of the nation-states in the Middle Eastern Arab-Islamic region. In order to fathom national identities in the basic law of government (or the constitution) in the region, this paper attempts to analyze the Basic Law of Government of the Kingdom of Saudi Arabia. In so doing, it endeavors to understand how Islamic shar‘ī principles are reflected in the Kingdom’s Basic Law of Government, and how they regulate the people of the Kingdom.

This paper aims to probe the effect of SQ in the rat liver which pretreated with CP was examined by transmission electron microscope. In the A group, the difference between the normal and the treated groups were not detected at 24 hours, but the few mitochondria were expanded at the 72 hours. In the B group, the cisternae of rough-surfaced endoplasmic reticulum were partially destructed and attached ribosomes were remarkably decreased at 24 hours. A number of the mitochondria were dilated and increased in number, the filamentous materials also detected at 72 hours. These results suggest that SQ is not only concerned with construction of the membrane of the cell organelles but also decreased the cellular toxicity in the hepatic cells.

Aim : To investigate the hepatotective effect of Gardenia jsaminodes and Glycine max aqueous extract against D-galactosamine (d-GalN, 300mg/kg body weight) was administered to the male Sprague Dawley (SD) rats. Materials and Methods : The study was carried out on male SD rats (age matched, weight $250{\pm}10g$). Experimental groups divided four: Normal group (Nor) was administered saline, Control (Con) group was administered saline after d-GalN treatment. Experimental group (Exp) was administered Gardenia jsaminodes (200 mg/kg; Ga group), Glycine max (700 mg/kg; Gl group), and Gardenia jsaminodes+Glycine max (200 mg/kg+700 mg/kg, GG group) during 14 days(n=5). Results : d-GalN administration induced hepatotoxicity in rats which was manifested by increased levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase but decreased total cholesterol and triglyceride. Treatment with Gardenia jsaminodes extract significantly protected the liver in d-GalN administered rats. Conclusion : Gardenia jsaminodes aqueous extract and Gardenia jsaminodes+Glycine max extract possesses hepatoprotective potential, thus validating its use in alleviating toxic effects of d-GalN.

N/A Background : Seborrheic dermatits and atopic dermatitis are clinically different diseases, but symptoms and signs of atopic dermatitis often can be found simultaneously in patients with seborrheic dermatitis. Objective : The aim of this study was to investigate if patients with seborrheic dermatitis have the symptoms and sign of atopic dermatitis at the same time, and to measure the levels of serum IgE and eosinophil counts. Methods : Sevently eight patients with seborrheic dermatitis on the scalp and face, 64 patients with atopic dermatitis and 88 normal subjects were observed clinically by the dermatologist and studide statistically using questionnaires. Levels of total IgE and eosinophil counts were measured by blood sampling in the total number of subjects. Results : Among 20 items of the questionnaire regarding the symptoms and signs of atopic dermatitis, 6 items were more frequent in only the atopic patients than in the normal control, 2 items were more frequent in only the seborrheic dermatitis patients and 8 in both diseases. The mean levels of serum IgE in seborrheic dermatitis patients were lower than in atopic patients, but significantly higher than that of the normal control and 21.3% of those had IgE levels above the normal range. When we classified the seborrheic dermatitis patients according to the combined skin diseases, the mean levels of IgE were highest in the patients with dermatitis and male pattern bladness, but the value was not significant compared to that of the normal control. The mean levels of eosinophil counts in seborrheic dermatitis patients were higher than in the normal control, but it was not significant statistically. Conclusion : According to the results of the study, the patients with seborrheic dermatitis showed a higher incidence of symptoms and signs of atopic dermatitis and higher levels of serum IgE than the normal subjects. Further studies will be needed to elucidate the relationship between seborrheic dermatitis and atopic dermatitis. (Korea J Dermatol 1999;37(9) : 1269∼1275)

항엽산제에 대한 세포의 저항성 기작

김정상(Jong-Sang Kim) 한국식품영양과학회 1994 한국식품영양과학회지 Vol.22 No.6

One of the major problems of cancer chemotheraphy is the development of drug resistance in tumors, resulting in reduced responsiveness to subsequent treatments. The folate antagonists are being used to treat such diverse illnesses as cancer, leukemia, psoriasis, rheumatoid arthritis, etc. Previous studies have established that resistance to antifolates may occur in mammalian tumor cells by one or more of five mechanisms : (a) an increase in the levels of the target enzyme, generally as a consequence of gene amplification; (b) an alteration in the target enzyme, leading to an enzyme with a decreased binding affinity for the drug; (c) a decrease in the uptake of the drug into the cells; (d) increased extrusion of drugs out of cells; (e) impaired ability to polyglutamylate the parent drug which is capable of being intracellularly metabolized to longer chain length.
