This study was carried out to obtain basic informations for gene action of quantitative characters including shattering resistance. The parental varieties used for $5{\times}5$ half diallel crosses were 'Yangbaek' and 'Ansan' of normal type, 'Suwon177' and 'Suwon195' of placenta adhesion type (PA) and 'SIG960320-5-1-1' of indehiscent type (ID). PA and ID type are shattering-resistant sesames, and Yangbaek and Ansan are shattering sesames. All the characters were sufficient to the assumption for diallel analysis in this experiment. Over dominance was exhibited by the number of capsules per plant, while partial dominance by plant height, capsule setting stem length, grain yield per plant and shattering rate, complete dominance by the number of branches per plant. Additive effect was higher than dominance in shattering rate. High shattering rate was dominant over low shattering rate. Suwon 195, shattering resistant sesame, showed to have the many recessive genes which reduced the shattering rate of sesame seed. Broad sense heritability for all the characters was more than 0.8. Narrow sense heritability for the number of branches per plant, the number of capsules per plant, grain yield per plant and shattering rate was 0.45 to 0.63, and plant height and capsule setting stem length was more than 0.8.

The study was undertaken to see the effect of elevated feeding during pre-partum or pre- as well as post-partum period on the productive and reproductive performance of crossbred cows. The experiment lasted for 60 d pre-partum to 120 d post-partum. Eighteen dry pregnant crossbred cows divided into three equal groups were fed either as per NRC feeding standard (C) or 20% above NRC during 60 d pre-partum ($T_1$) or fed 20% above NRC during both 60 d pre-partum to 120 d post-partum ($T_2$) period. During prepartum period body weight gain was significantly ($p{\leq}0.05$) higher in $T_1$ and $T_2$ groups than that of control group. The animals fed at higher plane of nutrition ($T_1$ and $T_2$) took significantly lesser time for complete relaxation of pelvic muscles, act of calving and for expulsion of placenta than that of control group. Moreover, such cows delivered 2 to 3 kg heavier calves as compared to normal fed dams. During post-partum period, the average daily milk yield was significantly higher in $T_2$ group than that in $T_1$ and control groups. The peak yield was significantly higher in $T_2$ group, it took longer time to reach peak production but it was more persistent in this group as compared to $T_1$ and control groups. Average milk fat, solids-not-fat (SNF) and total solids were significantly higher in $T_1$ and $T_2$ groups as compared to control group. Body weight losses incurred during early lactation were not even compensated by end of 4th month of lactation in C and $T_1$ groups whereas the animals in $T_2$ group gained 2.0 kg. The 1st post-partum estrus and conception rate were better in high fed groups ($T_1$ and $T_2$) than that of control group. The returns over feed cost of milk production were higher in $T_2$ group followed by $T_1$ and control groups indicating the advantage of elevated feeding during pre- and post-partum periods.

Background: Melanoma antigen genes (MAGE) are expressed in many human malignant cells and are silent in normal tissues other than in testis and in placenta. But MAGE expression in benign lung diseases, such as pulmonary tuberculosis or cases with severe inflammation, needs further evaluation to overcome false-positive findings. We evaluated detection rates of the melanoma antigen genes (MAGE) RT-nested PCR in bronchoscopic washing samples from patients with benign lung disease, as well as in patients with malignancies. Methods: Bronchial washing fluid from 122 patients was used for cytological examination and MAGE gene detection using RT-nested-PCR of common A1-6 mRNA. We compared the results from the RT-nested PCR and the pathologic or bacteriologic diagnosis. We also analyzed the expression rate and false positive rate of MAGE gene. Results: Among 122 subjects, lung cancer was diagnosed in 23 patients and benign lung disease was diagnosed in 99 patients. In patients with lung cancer, the positive rate of MAGE expression was 47.8% (11/23) and in benign lung disease group, the expression rate was 14.1% (14/99). Among benign lung disease group, the expression rate of MAGE gene (25.0%) in patients with pulmonary tuberculosis (11/44) was especially high. Conclusion: MAGE A1-6 RT-nested PCR of bronchial washing fluid can be used as a complementary method in lung cancer, but that test results in a high false positive rate in tuberculosis patients.

Objectives: This study aimed to identify the current use of Korean medicine for obesity and its effect for women in climacteric period. Methods: We studied women aged 45-55 who visited Daejeon Korean medicine Hospital of Daejeon University to lose body weight from January 1, 2021 to December 31, 2022 via an analysis of the medical records. The treatment duration was continuous for more than 2 weeks, and a body composition was measured by Inbody 770 at 2 to 4 weeks after the first visit. Results: 28 patients were finally selected and their average age was 49.32±3.38 years. Based on the body mass index (BMI) classification, 19 were in the 1st obesity group, 5 in the 2nd obesity group, 3 in the overweight group and 1 in the normal group. Patients usually complained comcomitant symptoms, and the symptoms of menopausal disorder was the most frequent. The average treatment duration was 3.68±0.67 weeks and the average treatment frequency was 3.93±0.98 times. All patients took herbal medicines Gambi-tang and 23 took modified fasting therapy including Gamro-su. 14 were treated by whole body far-infrared therapy and 6 were gotten partial obesity treatment. Among patients treated for accompanying symptoms, menopausal disorders were the most common (35.71%), and herbal medicine such as Gamisoyou-san, Hominis Placenta Pharmacopuncture, moxibustion, and cupping were used. After treatment, on average, body composition changed significantly; body weight 3.28±1.82 kg, BMI 1.36±1.04 kg/m², body fat 1.70±1.67 kg, skeletal muscle mass 0.81±0.91 kg, abdominal circumference 2.04±2.6 cm, and visceral fat area 8.91±12.83 cm². Conclusions: We analyzed general characteristics, BMI distribution, types of Korean medicine treatment and change of body composition. This study could be used as reference to provide practical data of treatment for obese women in climacteric period.

Members of the glycoprotein family, which includes CG, LH, FSH and TSH, comprise two noncovalently linked $\alpha$- and $\beta$-subunits. Equine chorionic gonadotropin (eCG), known as PMSG, has a number of interesting and unique characteristics since it appears to be a single molecule that possesses both LH- and FSH-like activities in other species than the horse. This dual activity of eCG in heterologous species is of fundamental interest to the study of the structure-function relationships of gonadotropins and their receptors. CG and LH $\beta$ genes are different in primates. In horse, however, a single gene encodes both eCG and eLH $\beta$-subunits. The subunit mRNA levels seem to be independently regulated and their imbalance may account for differences in the quantities of $\alpha$ - and $\beta$ -subunits in the placenta and pituitary. The dual activities of eCG could be separated by removal of the N-linked oligosaccharide on the $\alpha$-subunit Asn 56 or CTP-associated O-linked oligosaccharides. The tethered-eCG was. efficiently secreted and showed similar LH-like activity to the dimeric eCG. Interestingly, the FSH-like activity of the tethered-eCG was increased markedly in comparison with the native and wild type eCG. These results also suggest that this molecular can implay particular models of FSH-like activity not LH-like activity in the eCG/indicate that the constructs of tethered molecule will be useful in the study of mutants that affect subunit association and/or secretion. A single-chain analog can also be constructed to include additional hormone-specific bioactive generating potentially efficacious compounds that have only FSH-like activity. The LH/CG receptor (LH/CGR), a membrane glycoprotein that is present on testicular Leydig cells and ovarian theca, granulosa, luteal, and interstitial cells, plays a pivotal role in the regulation of gonadal development and function in males as well as in nonpregnant and pregnant females. The LH/CGR is a member of the family of G protein-coupled receptors and its structure is predicted to consist of a large extracellular domain connected to a bundle of seven membrane-spanning a-helices. The LH/CGR phosphorylation can be induced with a phorbol ester, but not with a calcium ionophore. The truncated form of LHR also was down-regulated normally in response to hCG stimulation. In contrast, the cell lines expressing LHR-t63I or LHR-628, the two phosphorylation-negative receptor mutant, showed a delay in the early phase of hCG-induced desensitization, a complete loss of PMA-induced desensitization, and an increase in the rate of hCG-induced receptor down-regulation. These results clearly show that residues 632-653 in the C-terminal tail of the LHR are involved in PMA-induced desensitization, hCG-induced desensitization, and hCG-induced down-regulation. Recently, constitutively activating mutations of the receptor have been identified that are associated with familial male-precocious puberty. Cells expressing LHR-D556Y bind hCG with normal affinity, exhibit a 25-fold increase in basal cAMP and respond to hCG with a normal increase in cAMP accumulation. This mutation enhances the internalization of the free and agonist-occupied receptors ~2- and ~17-fold, respectively. We conclude that the state of activation of the LHR can modulate its basal and/or agonist-stimulated internalization. Since the internalization of hCG is involved in the termination of hCG actions, we suggest that the lack of responsiveness detected in cells expressing LHR-L435R is due to the fast rate of internalization of the bound hCG. This statement is supported by the finding that hCG responsiveness is restored when the cells are lysed and signal transduction is measured in a subcellular fraction (membranes) that cannot internalize the bound hormone.

Combining ability and heterosis for $F_{1}$ population obtained $5{\times}5$ half diallel cross in sesame were estimated for six quantitative characters. The parental varieties used for diallel cross were Yangbaek and Ansan of normal type, Suwon 177 and 195 of placenta adhesion type (PA) and SIG960320-5-1-1 of indehiscent type (ID). PA and ID type are shattering-resistant sesames and Yangbaek and Ansan are shattering sesames. The high heterosis of $F_{1}$ hybrids was expressed in the number of capsules per plant (NC), grain yield per plant (GY) and number of branches per plant (NB). Shattering.ate (SR) showed high positive heterosis toward increase of seeds shattering in all the combination of $F_{1}$ generation which was presumed because the characters connected with shattering resistance of seeds were governed by recessive gene. At the analysis of combining ability, highly significant general combining ability (GCA) effects were observed on all the characters in $F_{1}$ generation, significant specific combining ability (SCA) effects were observed on the NC, GY and SR. GCA variances were greater than SCA variance, which suggested that additive gene effects were greater than other nonadditive gene effects. Considering the estimated GCA effects, Suwon 195 (PA type) was found to be good parent for SR and GY, SIG960320-5-1-1 (ID type) was poor for GY and plant height. SCA effect for NC was great in Yangbaek/Suwon 195, SCA for GY was great in Ansan/SIG960320-5-1-1, and SCA for decrease of SR was great in Ansan/Suwon177.
