This study was conducted to find out the difference in the use of latissimus dorsi muscle and forearm muscles between skilled and unskilled people when performing pull-up. The subjects of the study were one skilled in the department of sports science at Soon-chun-hyang University, one unskilled person who had no problems with the musculoskeletal system over the past year, and a total of two people who could do pull-ups more than 20 times. A total of one experiment was conducted, and two tests were conducted. The electromyogram data of the light back and forearm muscles were compared using a wireless electromyogram measurement device (EMG). As a result of the study, first, when performing pull-up, the unskilled person performed the movement with the strength of the forearm muscle rather than the light back muscle compared to the skilled person. Second, when performing pull-up, the skilled person showed similar use of force in both pull-up movements, and for non-skilled people, the activity of the forearm muscle in the second movement was significantly increased.

Chitosan is the deacetylated product of chitin. Chitosan and its derivatives have many properties that make them attractive for a wide variety of health applications. We reported recently that water soluble chitooligosaccharides have hepatoprotective effect on ethanol induced liver injury in the mouse. The current study examined the effect of water soluble chitooligosaccharides on CC1₄-induced liver injury in rats. Male Sprague-Dawley rats were orally treated with CC1₄without or with administration of 5% chitooligosaccharides. After 5 weeks after CC1₄treatment, the histological sections and the expression of mRNA of interleukin-12(IL-12), hepatocyte growth factor(HGF), and tumor necrosis factor(TNF- ) were examined. The liver section of rats supplemented with chitooligosaccharides showed attenuated effects of the necrosis, steatosis, cirrhosis compared with those of non-supplemented rats. The level of TNF- mRNA in CC1₄-treated rats were higher than those in the rats supplemented with chitooligosaccharides, while the levels of IL-12 and HGF mRNA were higher in the rats supplemented with chitooligosaccharides than those of in CC1₄-treated rats. These findings suggested that water soluble chitooligosaccharides may have a hepatoprotective activity against CCl₄-induced liver injury in rats.

Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

비선택성 제초제인 bialaphos는 고등식물에 있어서 glutamine 합성을 억제하여 식물체를 고사시킨다. Acetyltransferase에 의해 encoding된 bialaphos 저항성 유전자는 세균 Streptomyces hygroscopicus SF1239로부터 cloning된 것을 사용하였다. Bialaphose 저항성 유전자를 Agrobacterium 감염법을 이용하여 국내에서 재배되는 벼(동진)에 도입한 결과 약 30%정도의 형질전환 식물체를 얻을 수 있었다. T_1세대의 17개체는 hygromycin과 bialaphos에 대한 저항성 유전형질이 3 : 1로 분리되었다. 또한 Southern 분석을 실시한 결과 wild type의 식물체에서는 Bar 유전자의 검출을 볼 수 없었으나 형질전환 식물체의 경우 Bar 유전자의 검출이 가능하였다. T_3 세대의 형질전환 식물체와 wild type의 식물체를 포장상태에서 비선택성 제초제인 바스타를 살포하고 3주 후에 관찰한 결과 형질전환 식물체는 외형적으로 아무런 피해를 받지 않고 정상적으로 생장하였으나, wild type의 식물체와 잡초는 모두 고사하였다. 이상의 결과를 종합해보면 hygromycin과 bialaphos 저항성 유전자는 Agrobacterium 감염법을 이용하여 단자엽 식물인 벼에 도입할 수 있다는 것을 보여준 것이며, 또한 bialaphos 저항성 유전자가 식물에 도입됨으로써 비선택성 제초제에 대한 저항성 식물을 개발 할 수 있다는 것을 보여 주었다. The bialaphos is a potent inhibitor of glutamine synthease in higher plants and is used as a non-selective herbicide. We have used the bialaphos resistant gene (Bar) encoding for an acetyltransferase isloated from Streptomyces hygroscopicus SF1293. Callus derived from mature seeds of rice (Oryza sativa L. cv. Dong Jin) were co-cultivated with Agrobacterium tumefacieus EHA101 carring a plasmid pGPTV-HB containing genes for hygromycin resistance (HygR) and Bar. Transgenic plants showing in vitro resistance to 50 mg/L hygromycin and 10 mg/L bialaphos were obtained by using a two-step selection/regeneration procedure. Transformation efficiency of rice was about 30% which was as high as reported in other dicotyledons. Progenies (T_1 generation) derived from primary transformant of 17 lines were segreagated with a 3 resistant:1 sensitive ratio in medium containing hygromycin and bialaphos. Stable integration of Bar gene into chromosomal DNA was proven by Southern blot analysis of genomic DNA isolated from T_2 progenies. Transgenic plants (T_3) grown in the field were resistant to bialaphos (Basta) at a dosage lethal to wild type plants.

Objectives : Cinnamomi Ramulus (CR), the young twing of Cinnamomi loureirii nees, has been used for treating symptoms related to pain. rheumatic arthritis and inflammation in Korean herb medicine. This study was carried out to investigate the anti-inflammatory effect of CR in vivo and in vitro. Methods : Extracts of CR were prepared and the chemical components of the extracts were examined by gas chromatography-mass spectrometry (GC-MS). The extracts were administrated to the rat paw edema model induced by carrageenan to evaluate the anti-inflammatory effect of CR. The expressions of nitric oxide (NO). prostaglandin E2(PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were also quantified in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages to survey the effect of CR in vitro. The main components were cinnamaldechyde and coumarin. Results : We examined the anti-inflammatory activity of the 80% ethanol extract of Cinnamomi Ramulus in vivo by using carrageenan-induced rat paw edema model. Maximum inhibition of 54.9% was noted at the dose of 1000㎎/㎏ after 2 hours of drug administration in carrageenan-induced rat paw edema and this showed a potent anti-inflammatory effect. Conclusions : The results showed that Cinnamomi Ramulus suppressed dose-dependently LPS-induced NO production in RAW 264.7 macrophages and also decreased iNOS protein expression. Cinnamomi Ramulus also showed a significant inhibitory effect in LPS-induced PGE2 production and COX-2 expression.
