Objective : Cubital tunnel syndrome, the most common ulnar nerve entrapment neuropathy, is usually managed by simple decompression or anterior transposition. One of the concerns in transposition is damage to the nerve branches around the elbow. In this study, the location of ulnar nerve branches to the flexor carpi ulnaris (FCU) was assessed during operations for cubital tunnel syndrome to provide information to reduce operation-related complications. Methods : A personal series (HJY) of cases operated for cubital tunnel syndrome was reviewed. Cases managed by transposition and location of branches to the FCU were selected for analysis. The function of the branches was confirmed by intraoperative nerve stimulation and the location of the branches was assessed by the distance from the center of medial epicondyle. Results : There was a total of 61 cases of cubital tunnel syndrome, among which 31 were treated by transposition. Twenty-one cases with information on the location of branches were analyzed. The average number of ulnar nerve branches around the elbow was 1.8 (0 to 3), only one case showed no branches. Most of the cases had one branch to the medial head, and one other to the lateral head of the FCU. There were two cases having branches without FCU responses (one branch in one case, three branches in another). The location of the branches to the medial head was 16.3±8.6 mm distal to the medial epicondyle (16 branches; range, 0 to 35 mm), to the lateral head was 19.5±9.5 mm distal to the medial epicondyle (19 branches; range, -5 to 30 mm). Branches without FCU responses were found from 20 mm proximal to the medial condyle to 15 mm distal to the medial epicondyle (five branches). Most of the branches to the medial head were 15 to 20 mm (50% of cases), and most to the lateral head were 15 to 25 mm (58% of cases). There were no cases of discernable weakness of the FCU after operation. Conclusion : In most cases of cubital tunnel syndrome, there are ulnar nerve branches around the elbow. Although there might be some cases with branches without FCU responses, most branches are to the FCU, and are to be saved. The operator should be watchful for branches about 15 to 25 mm distal to the medial epicondyle, where most branches come out.

춘잠기에 있어서의 가지뽕의 간벌수확의 효과와 합리적인 간벌방법을 구명하기 위하여 시험한 바 다음과 같은 결과를 얻었다. 1. 춘잠기에 있어서의 가지뽕의 간벌수확은 1주일 정도의 간격으로서는 가는 가지 간벌수확구를 제외하고는 별로 효과가 없다. 2. 가는 가지 간벌구는 표준구와의 사이에 유의차는 없지만 약간 증수가 되는 경향에 있고 특히 소량의 가지뽕이 필요한 4령기에 잔조를 벌채하게 되어 그 수확비율이 현실에 적합하다는 이점이 있다. 3. 굵은 가지를 간벌하는 것은 다른 어떠한 수확법보다 못하다. 수량이 많은 굵은가지를 간벌한 후 1주일 정도로서는 나머지 가는 가지의 발육이 크게 호전하지 못하는 까닭이라고 생각된다.

This study focused on researching the factors affecting retail banking efficiency of Vietcombank branches in the Mekong-Delta region. By collecting data from financial statements from 15 branches of VCB in the Mekong-Delta Region between 2015 and 2018, the paper applies DEA estimation to measure the effectiveness of retail banking activities and uses the Tobit regression model to identify factors affecting retail banking efficiency. The results demonstrate that the retail banking efficiency of branches averaged 52.5% during the period. The rating result shows the branches in An Giang, Can Tho, Dong Thap, Kien Giang, Long An, Phu Quoc and Tra Noc rank at the top technical efficiency. In group of medium efficiency, there are branches in Soc Trang, Tien Giang and Vinh Long. In the category of the poor efficiency are the branches in Bac Lieu, Ben Tre, Ca Mau, Chau Doc and Tra Vinh. The results also show that bank scale-related factors, capital adequacy, credit quality, time specific and region impact significantly the retail banking efficiency. The research not, only contributes to enriching the empirical research method but also is significant for the management activities in business developing strategies, improving the operational efficiency of Vietcombank in the region.

The present study reports morphology and developmental pattern off siliquosa cultured in a laboratory condition. The zygote was spherical with a diameter of 85 ${\mu}{\textrm}{m}$. During development the polarized zygote divided horizontally and the lower daughter cell divided horizontally into 2 cells. The upper cell was divided repeatedly in horizontal and vertical directions to form a cylinder-like structure, which subsequently developed into secondary and tertiary dichotomous branches. Optimum temperature for zygote release and fertilization was 25C. Injury inflicted by slicing was cured by epidermal differentiation, and adventitious branches; the branches emerging from the pith cells, however, developed no rhizoid. Adventitious branch formation rate was over 88% in all plates supplemented with 0.5 mg/L IAA and peaked at 98% under 0.5 mg/L IAA plus 0.5-5.0 mg/L NAA treatment. NAA stimulated the differentiation of adventitious branches at a wide range of concentrations, while IAA, 2,4-D and kinetin exhibited dose-dependent stimulation.

하잠기와 초추잠기에 각주마다 뽕나무지조중 잔가지와 정상가지 2개씩을 솎아베기하였을 경우에 가지의 발육과 수량에 어떤 영향을 미치는가를 조사한바 다음과 같은 결과를 얻었다. 1) 봄베기한 뽕나무에 있어서 하잠기에 솎아베기를 하고 추잠기(이 기간 42일간)에 수확을 한 경우에 있어서 (1) 추잠기까지에 그 평균조장이 19% 가 증가하여 솎아베기를 하지않은 경우의 증가율 8% 보다 11% 나 그 증가비율이 높았다. (2) 솎아베기를 하면 이것을 하지않은 경우에 비하여 하잠기와 추잠기의 합계수량에 있어서 유의성은 없지만 9% 정도 증수가 된다. 2) 여름베기한 뽕나무에 있어서 초추잠기에 솎아베기를 하고 추잠기(이 기간 15일간)에 수확을 하는 경우와 만추잠기(이 기간 29일간)에 수확을 하는 경우에 있어서 (1) 그 평균조장은 솎아베기를 한 경우나 하지않은 경우나 다 같이 추잠기까지는 6∼7%, 만추잠기까지는 8% 정도 증가하여 솎아베기의 효과를 인정할 수가 없었다. (2) 초추잠기와 추잠기의 합계수량은 솎아베기를 한 경우가 하지않은 경우에 비하여 6%가 증수가 되어 유의성은 없지만 증수의 경향이 있고 초추잠인와 만추잠기의 합계수량은 솎아베기를 한 경우가 하지않은 경우보다 12%가 단수가 되어 5%의 수준에서 유의성이 인정되었다. (3) 솎아베기가 평균조장의 증가에는 별로 효과가 없지만 수량증가에는 효과를 나타낸 것은 솎아베기를 하므로 말미암아 뽕나무주내의 생활조건을 개선하여 광합성작용을 왕성하게 하므로써 엽중을 증가시킨 까닭이라고 생각된다.

Rice yields are determined by the number of spikes per unit area, the number of rice per grain, the rate of ripening, and the weight of brown rice gravel. Among these yield components, the most important factor that reflects the characteristics of rice is the number of rice per grain and the number of rice per grain. The characteristics of rice panicle are influenced by genetic factors rather than environmental factors and revealed that it had different genetic characteristics in each of Japonica, Indica and Japonica ${\times}$ Indica type. In general, the number of rice per grain is affected by number of secondary rachis branches and generated spikelets number of secondary rachis branches. This study conducted to investigate the characteristics of the grain according to the planting density of two varieties of Jap. ${\times}$ Ind. type. Number of primary rachis branches and number of primary rachis branches of Palbangmi variety were 9.9 ~ 10.6 and 53.4 ~ 58.5, respectively. Number of secondary rachis branches and number of secondary rachis branches were 25.8 ~ 29.6, 85.8 ~ 101.4, Number of tertiary rachis branch and number of tertiary rachis branches were 1.0 ~ 2.4 and 2.0 ~ 6.1, respectively. Number of primary rachis branches and number of primary rachis branches of Semimyeon variety were 8.6 ~ 9.5 and 43.1 ~ 47.8, respectively. Number of secondary rachis branches and number of secondary rachis branches were 21.0 ~ 24.9, 66.2 ~ 77.9, Number of tertiary rachis branch and number of tertiary rachis branches were 1.6 ~ 2.6 and 3.8 ~ 6.3, respectively. The ratio of the spikelets of primary, secondary and tertiary rachis branches of Palbangmi variety were 37.7 ~ 39.4, 58.0 ~ 60.5 and 1.2 ~ 3.1%, respectively, and those of Semimyeon were 40.1 ~ 42.6 55.0 ~ 56.4 and 2.5 ~ 3.4% respectively. Number of primary and secondary rachis branches of Palbangmi variety showed no difference among the planting density. However, generated spikelets number of secondary rachis branches and ripening rate were higher with lower planting density. The number of secondary rachis branches and generated spikelets number of secondary rachis branches per acre decreased as the planting density increased in the Semimyeon variety

Shiranuhi is a fruit of Citrus species widely cultivated in Jeju Island, Korea. From an extract of Shiranuhi tree branches were identified five polymethoxyflavones possessing anti-inflammatory effects; nobiletin (1), sinensetin (2), tetramethylscutellarein (3), 6-hydroxy-5,7,3',4'-tetramethoxyflavone (4) and 5-desmethylsinensetin (5). Evaluation of the activities was conducted by monitoring the production of nitric oxide (NO), prostaglandin E₂ and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) as well as the levels of iNOS and COX-2 protein expression in LPS-induced RAW264.7 cells. Among the isolates, the compound 4 exhibited the most significant NO inhibition, and suppressed the levels of iNOS and related cytokines. Therefore, it was suggested that the extract and constituents from Shiranuhi tree branches could be useful as anti-inflammatory ingredient.

Background: In this study, we investigated the antibacterial and nitric oxide (NO) production inhibitory activities of 75% ethanol extract of Prunus sargentii branches and its fractions against acne pathogens. Methods and Results: The antibacterial activity against acne causing pathogens was determined using the disc diffusion assay. The ethyl acetate fraction showed higher activities against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis than those shown by other fractions. In the DPPH radical and NO scavenging assays, the butanol fraction showed strong DPPH radical and NO scavenging abilities. These activities were related to the total polyphenol and flavonoid contents of butanol fraction. On the other hand, the chloroform and ethyl acetate fractions exhibited the highest NO production inhibitory activity in Lipopolysaccharide (LPS)-stimulated Raw 264.7 cells compared to those exhibited by other fractions. Conclusions: The extract and its ethyl acetate fraction from the branches of P. sargentii exhibited antibacterial activity and could be used as functional materials in antimicrobial related fields. Moreover, the chloroform and ethyl acetate fractions are potential antiinflammatory agents and butanol fraction acts as an effective radical scavenger.

Trigeminal neuralgia (TN) is neuropathic pain that affects the trigeminal nerve branches. Facial pain experienced by patients with TN is typically intense and excruciating. The second and third branches (maxillary and mandibular) are commonly affected. This case report focuses on the potential treatment options for acute TN attacks involving these branches. The proposed approach involves extra-oral peripheral blocks using local anesthetics. Pain levels were measured using a visual numeric scale (VNS) with potential side effects and other relevant documented information. The patients showed responses from high pain levels to almost complete remission (from 8 to 2 and from 10 to 2 on the final VNS), with no significant side effects. This technique provides immediate pain relief and complements oral medications by offering comfort and confidence until the desired drug effect is achieved.

우리는 미국선녀벌레의 월동알 조사를 하는데 있어 조사자의 공통된 조사방법을 제시하고자 전국적으로 분포하는 아카시나무의 가지를 부위별로 조사하였다. 조사한 총 표본수는 189개 샘플이었고 가지는 가시밑둥, 잔가지밑둥, 가지표면 세부분으로 나누어 알을 조사하였다. 모든 부위에서 알이 존재하지 않는 샘플을 포함했을 때는 모두 정규분포를 따르지 않았으나 알이 존재하지 않는 샘플을 제외했을 때는 가지밑둥과 잔가지밑둥에서 조사된 알은 정규분포를 따랐다. 가지의 굵기에 대한 정규성 정도는 없었다. 가지밑둥과 잔가지밑둥에서의 미국선녀벌레 알의 밀도는 가지표면에서 보다 유의성 있게 높은 밀도를 보여주었고 가지의 굵기별 조사에서는 유의성이 없었다. 따라서 미국선녀벌레가 주로 산란하는 아카시나무는 전국적으로 분포하고 있는 수종으로 아카시나무 가지의 굵기와 상관없이 가시밑둥과 잔가지밑둥에서 미국선녀벌레 알을 조사하는 것이 밀도 추정의 정밀도를 높여 정확한 한반도 분포 특성과 발생예측을 위한 조사방법으로 크게 기여할 것으로 판단된다.
