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.

The experiment was carried out to establish a reasonable harvesting method of mulberry shoots with branches by thin out in spring, comparing with thin-out harvest, and the results are as follows. 1. In spring, the thin-out harvest showed no remarkable effect in the results of seven days interval cutting down, except for the treatment of thinning-out thinner branches. 2. There was no significance between the control and the thinning-out thinner branches, but a tendency to increase a little harvest. Therefore, few shoots of thin branches should be cut down for the 4th instarlarvae and the rest of branches for the 5th instarlarvae. 3. The thin-out of the thicker branches showed the worst result of others, because it can hardly expect for 7 days after cutting down the thicker branches.

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.

This work was carried out to investigate how the effects on the growth af branches and the yield of mulberry leaves are shown, when two of each dwarf and normal branches are thinned out in sumner or early autumn. The results obtained are summarized as follows. 1) In mulberry trees after spring pruning: in case of thin out branches in summer and harvest in autumn (42 days after treatment), (1) The average length of branches in thin out trees showed 19% increase by autumn, which turned out to be 11% higher than that of non-thin out did (8%) (2) The thin out treated mulberry trees presented 9% increase in total yields of summer and autumn, when compared with those of the non-thin out trees. 2) In mulberry trees after sumner pruning: in case of thin out branches in early autumn and harvest either in autumn (15 days after treatment) or in late autumn (28 days after treatment), (1) The average length of branches showed about 6∼7% and 8%, intercase by autumn and late autumn, respectively. Thus no effects of thin out treatment could be recognized in growing of branches. (2) The thin out treated mulberry trees presented about 6% increase in total yields of early autumn, showing no significance through, when compared with those of ron-thin out treatment. Whereas the total yields of early autumn and late autumn showed 12% increase with significance at the level of 5% by thin out treatment. (3) As above mentioned, the thin out of mulberry branches brought about a good effect on yields of mulberry leaves, though less on average length of branches. It may be considered that the thin out treatment makes improve the living condition in mulberry trees and in turn induces photosynthesis actively, which results in increase the weight of leaves.

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.

We surveyed branches of acacia trees distributed nationally in Korea to establish a common survey method that can be used by investigators to monitor for over-wintering Metcalfa pruinosa eggs. A total of 189 samples was examined, and the number of eggs on the surfaces of the branches, bases of thorns and bases of twigs was recored. When including samples in which no eggs were found at all investigation sites, none of the data followed the normal distribution. However, when samples in which no eggs were found at all sites were exclued, the density of eggs investigated at the thorn bases and twig bases followed the normal distribution. When the density of eggs was sorted based on the thickness of the branches on which they were found, these data did not follow the normal distribution. The density of M. pruinosa eggs at the thorn bases and twig bases was significantly higher than that on the branch surfaces, but there was no significant difference among branches of different thicknesses. Therefore, monitoring for M. pruinosa eggs at the thorn bases and twig bases of the nationally distributed acacia tree, irrespective of the thickness of the branches, will be able to increase the precision with which the density of this insect's eggs could be estimated. It is thus expected that this method will contribute to developing methods to better characterize the distribution and predict the occurrence of this.
