Objective : We try to find out the literature and clinical evidences of seasonal formula through the analysis of the addition and subtraction of medical herbs in the formula according to the season. Method : In this study, we analyzed 122 seasonal prescriptions from "Dong-uibogam(東醫寶鑑)", "Bang-yakhappyeon(方藥合編)", "Jeongchijunsueng(證治準繩)", "Dangyesimbeop(丹溪心法)", "Uihakimmun(醫學入門)", "Uihakjeongjeon(醫學正傳)", "Gyeong-akjeonseo(景岳全書)" and "Taepyeonghyeminhwajegukbang(太平惠民和劑局方)". Results : In spring, pungent-warm herbs such as the dried rhizome of cnidium officinale Makino, the dried root of SEdebouriella divaricata (Turcz.) Schischk. are used. In summer, bitter-cold such as the dried root of Scutellaria baicalensis Georgi, the dried rhizome of Coptis chinensis Franch. or pungent herbs such as the dried aerial part of Elsholtzia splendens Nakai, the dried ripe seed of Dolichos lablab L. are added. In fall and winter, pungent-bitter-hot herbs such as the dried ripe fruit of Evodia rutaecarpa Benth., the dried rhirome of Zingiber officinale Rosc. are used. Conclusions : In this paper, we have shown that several medical herbs could be added and subtracted in the formula according to the season because they have the seasonal characteristic Gi or treat seasonal pathogens.

In this study, an experiment was conducted to investigate the annual reproductive cycle of a Korean flat bittering, Acheilognathus rhombeus, from Ogok-myeon located in Seomjin River. The reproductive cycle was examined histologically regarding water temperature and day length of the habitat, the gonadosomatic index (GSI), and developmental characteristics of female and male gonads. The maximum GSI was found to be 3.50±0.53 and 1.36±0.14 for females and males, respectively, when the water temperature and day light was 16.9℃ and 11.3 hours, respectively in October 2018. On the other hand, the minimum GSI was found to be 0.16±0.09 and 0.69±0.15 for males and females in December 2018 and February 2019, respectively. The ovipositor of females appeared from August to November 2018. We compared and calculated the stages of germ cell developmental characteristics in the testis and ovaries to determine the reproductive cycle. According to the result, we classified the female A. rhombeus reproductive cycle into four phases, which are ripe and spawning phase (October), degenerative phase (November to December), growing phase (January to March) and mature phase (April to September). The annual reproductive cycle of male A. rhombeus was categorized into four phases: mature phase (June to October), degenerative phase (November to March), resting phase (April) and growing phase (May). The Korean flat bittering is an autumn-spawner as the main spawning season in October. In male, testicular spermatogonia appeared all year-round, and the ripe and releasing phase, which is characteristics of the spawning season in other fish, did not appear.

Maturity and spawning of the snailfish, Liparis ochotensis was investigated based on samples collected by gill net in the East Sea of Korea from December 2008 to December 2009. The average total length of L. ochotensis was 63.4 cm and 64.1 cm for females and males, respectively. Gonadosomatic index (GSI) began to increase in July, reaching a maximum in November, then began to decrease in December. Monthly changes in the GSI values of L. ochotensis were similar for females and males. Annual reproductive cycle of this species can be divided into five successive stages in females: early growing stage (May), late growing stage (June to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Males show four successive stages; growing stage (May to July), mature stage (August to September), ripe and spent stage (September to December), and recovery and resting stage (January to April). Relationship between total length (TL) and fecundity (F) was F=$0.00003TL^{4.002}$ ($R^2$ = 0.703), and F increased with TL. Total length at 50% group maturity was estimated to be 55.8 cm. Our findings suggest that the spawning period takes place from September to December, with the main spawning period occurring from October to December.

The plant Rubus species (Rosaceae) mainly contains $19{\alpha}-hydroxyurane-type$ triterpenoids $(19{\alpha}-HUT)$ as bioactive components. Available functional food includes blackberry (the fruit of thornless Rubus sp.), red raspberry (R. idaeus) and black raspberry (R. occidentalis). However, the fruit of R. coreanus, which is used in Korea as a functional food, substitutes black raspberry. Rubi Fructus, which has been traditionally used as an oriental medicinal drug, designates only unripe fruit of R. coreanus but not its ripe fruit which indicates that it needs high content of $19{\alpha}-HUT$ as a crude drug. Throughout our experiment, we found that ripe fruits contain very little amount of $19{\alpha}-HUT$ when compared to unripe fruits. In addition, various and rich $19{\alpha}-HUT$ has been reported from Rubus species. The most common structure of $19{\alpha}-HUT$ of Rubus species, euscaphic acid or tormentic acid with $3{\alpha}-OH$ or $3{\beta}-OH$, respectively, can be glycosylated or oxidized to produce a number of $19{\alpha}-HUTs $as euscaphic acid and tormentic acid derivatives and even esterified to form dimeric triterpenoids. In this review, the bioactivity and biosynthetic pathway and chemical characterization of $19{\alpha}-HUTs$ found in Rubus species are discussed.

우럭, Mya arenaria은 자웅이체로서 난생이다. 생식소는 소화맹낭과 근육층 사이에 분포하고 있다. 난소와 정소는 작은 소낭들로 구성되어 있고, 성숙하면 비후된다. 이들 소관의 내강상피가 생식상피 기능을 하고 있다. 난소 및 정소의 발달에는 간충조직과 과렵세포들이 영양세포로 관여하고 있으며, 방란 방정을 마친 생식소는 완전 퇴화하고, 짧은 회복기를 거쳐 생식소낭의 형태를 갖추며 새로 분화 재배치된 망 상결체조직에서 생식소가 신생되어 기능을 발휘한다. 비만도는 99년 4월 (0.054)에 최고값을 나타내었으며, 방출기가 종료된 직후 1998년 10월에 최저값 (0.030)을 보였다. 완숙난은 $60{\mu}m$ 전후로 하나의 큰 인을 가진다. 암수의 성비는 0.89:1로 수컷이 약간 높게 나타났다. 생식주기는 초기활성기 (2월$\~$3월), 후기활성기 (4월$\~$8월), 완숙기 (9월),부분방출 및 방출기 (9월$\~$10월) 그리고 비활성기 (11월$\~$1월) 등의 연속적인 주기로 구분할 수가 있다. 주산란기는 $9\~10$월로 추계산란종이다.

Extent of reduction in protein digestibility by Godulbaegi(lxeris sonchifolia H.) kimchi powder appeared to be related to the kimchi weight-to-protein weight ratio, the kind of protein sources, part of plants and fementation period. In vitro digestibilities of protein were significantly(p<0.05) reduced as the freeze dried kimchi powder weight-to-protein ration increased from 0.5 : 1.0 to 1.0 : 1.0 for all Godulbaegi samples and protein sources. Overall digestibility of protein sources in the presence of kimchi powder, the reduction ranked in the following order : soybean>casein>beef>squid. Lower(p<0.005) reduction occurred for each protein source when raw plant was exchanged for kimchi products. Some greater reduction of digestibility was noted in young plants and leaf samples than ripe or root samples. Trypsin inhibitor, which expressed as soybena trypsin inhibitor, was inversely related(r=0.8437) to in vitro protein digestibility of casein in the presence of Godulbaegi kimchi powder. More than three times of total polyphenols contained in leaves than in roots. Young leaves had 30% more total polyphenols(37.64mg/g sample) than that in ripe ones. Soaking in 5% NaCl solution for 24 hrs was markedly reduced in total polyphenols as 73% for leaves and 33% for roots. Remarkable reduction in total polyphenols was not checked during fermentation followed after soaking. Trypsin inhibitor content correlated well(r=0.8873) with total polyphenols in all of Godulbaegi samples.

To investigate the aroma and quality characteristics of wine bestowed by the degree of ripening of Cheongporang grapes, the general quality composition, color, organic acid, physiological activity, aroma component and sensory evaluation were analyzed. The general characteristics of the wine assessed were pH 3.34~3.50, total acidity 0.46~0.67%, color intensity 0.074~0.116, lightness 98.99~99.74, redness -0.39~0.01, and yellowness was 1.52~3.10. Malolactic fermentation was not relative to the contents of malic acid and lactic acid. The total polyphenol content and antioxidant activity were lowest in C3 wines made with ripe grapes and highest in C4 wines made with mixed grapes. Aroma analysis identified 6 alcohols, 15 esters and 5 miscellaneous compounds. Compounds with higher odor activity value (OAV) were 3-methyl-1-butanol, ethyl butanoate, isopentyl acetate, ethyl hexanoate, ethyl octanoate, ethyl decanoate and octanoic acid. The C4 wine, a mixture of grapes with different degrees of ripening, had the highest ester content and ratio. The lowest values were found in the C3 wine made with ripe grapes. Results of the sensory evaluation related the C4 wine, containing a large amount of ester compounds having high OAV values as the aroma component, as the best and most preferred wine.
