Changes in physicochemical properties of brown rice (Chu-chunk byeo, Japonica type) kept at $4^{\circ}C,\;20^{\circ}C,\;30^{\circ}C\;and\;40^{\circ}C$ in laminated film (4 layer) pouches were analyzed. Hardness of brown rice grain increased during storage periods. In case of color changes, 'L' value increased during storage below $30^{\circ}C$, and decreased after three months at $40^{\circ}C$. The 'a' value did not change below $30^{\circ}C$, but increased at $40^{\circ}C$. The 'b' value increased under all storage conditions. Percent germination was above 97% below $20^{\circ}C$ regardlesss of storage period and was inhibited by heat above $30^{\circ}C$. The rice did not germinate after one month storage at $40^{\circ}C$ Gelatinization enthalpy and gelatinization peak temperature by DSC of brown rice powder decreased during storage. As a result, storage below $20^{\circ}C$ in laminated film pouch is recommended far brown rice.

The abolishment of the red ginseng monopoly act by the Korean government in 1996 resulted in a drastic change in the Korean ginseng industry, leading to a significant increase in the market size and consumption of ginseng products. Red ginseng is most popular type, with approximately 74% of harvested fresh ginseng being processed into various red ginseng products. Since 1997, there has been a substantial increase in the cultivation of ginseng for production of red ginseng, which, in turn, has contributed to the proliferation of ginseng processing companies. To investigate the products of ginseng manufacturing businesses, we select 200 companies primarily engaged in ginseng processing or specializing solely in ginseng. Our survey on the status of ginseng industry covered 8 different categories. 1) Root ginseng: There were 66 companies involved in manufacturing red ginseng root, accounting for 33.0% of all surveyed companies. This was followed by black ginseng root with 36 companies (18.0%) and red ginseng fine roots with 22 companies (11%). 2) Red ginseng products: A total of 144 companies were involved in manufacturing red ginseng pouches, making it the most common product category. This was closely followed by 142 companies producing pure(100%) red ginseng extract concentrate. 3) Fermented red ginseng products: Companies producing fermented red ginseng extract concentrate products were the most numerous, totaling 26. Following this, companies producing fermented red ginseng stick and pouch products were next in line. 4) Ginseng products: There were 15 companies involved in the production of ginseng products, with the majority focusing on ginseng tea. 5) Black ginseng products: Companies producing black ginseng extract concentrate were the most numerous, with 31 companies, followed by 26 companies producing black ginseng extract pouches. 6) Taegeuk ginseng products: Only 5 companies were involved in the production of taegeuk ginseng products. 7) Fermented black ginseng, and 8) Ginseng berry products: These categories are manufactured by less than 5 companies each. However, the variety in ginseng berry products suggests the potential for future growth. In the 2000s, a trend emerged with the development of new processed products aimed at enhancing the functional components of red ginseng, and these products have captured the attention of consumers. However, this study primarily focuses on black ginseng, fermented red ginseng/fermented black ginseng, and ginseng berry products as they have exerted a significant influence on the overall ginseng industry.

Apoptosis, also known as cell suicide or programmed cell death, removes unwanted and genetically damaged cells from the body. Evasion of apoptosis is one of the major characteristic features of rapidly proliferating tumor cells. Chemopreventive agents inhibit or suppress tumor formation through apoptotic induction in target tissues. The aim of the present study was to investigate the pro-apoptotic potential of lupeol during 7,12-dimethylbenz(a) anthracene (DMBA) induced hamster buccal pouch carcinogenesis. Topical application of 0.5% DMBA three times a week for 14 weeks in the buccal pouches of golden Syrian hamsters resulted in oral squamous cell carcinoma. The expression pattern of apoptotic markers was analyzed using immunohistochemistry (p53, Bcl-2, Bax) and ELISA reader (caspase 3 and 9). In the present study, 100% tumor formation with defects in apoptotic markerexpression pattern was noticed in hamsters treated with DMBA alone. Oral administration of lupeol at a dose of 50mg/kg bw completely prevented the formation oral tumors as well as decreased the expression p53 and Bcl-2, while increasing the expression of Bax and the activities of caspase 3 and 9. The present study thus indicated that lupeol might inhibit DMBA-induced oral tumor formation through its pro-apoptotic potential in golden Syrian hamsters.

This study was carried out to evaluate the irritant potential of P-toothpaste in hamster cheek pouch. The test materials were applied once at the beginning of this study into right pouches of hamsters and maintained for 14 days. Animals were administered with P-toothpaste, Bamboo salt toothpaste, D.W. and control solution, respectively. In order to evaluate the irritant potential in mucosa of hamster cheek pouch, we observed clinical signs, morality, body weights and gross and histopathological findings for 14 days. In all groups, there were neither dead animals nor significant changes of body weights. In addition, there were no differences between D.W. and P-toothpaste treated group in gross and histopathological findings. Therefore, these results suggest that there was little irritant potential of P-toothpaste in hamster cheek pouch.

Effects of packing materials on the gas compositions in package of fresh peeled garlic (Allium sativum L.) were investigated. The fresh peeled garlics packed in $20,\;40,\;60\;{\mu}m$ LDPE and $30\;{\mu}m$ HDPE pouches were stored at $20^{\circ}C$, 76% RH. The variables including respiration characteristics, gas compositions, general appearance, and film permeabilities to $O_2$, $CO_2$ and $H_2O$ vapor were measured. A model was evaluated for the prediction of $O_2$ and $CO_2$ equilibrium concentrations inside packages and for the optimization of packaging parameters. Experimental and simulated gas composition results were found to be in good agreement. The $30\;{\mu}m$ HDPE pouch with 4% $O_2$ and 7.5%$CO_2$ equilibrium concentrations conferred the best appearance of peeled garlic, giving 6 days of storage life. As a result, MA seemed to have a beneficial effect on appearance of fresh peeled garlic, possibly due to reduced microbial activity.

This paper provides an overview of kimchi packaging technology, focusing on packaging materials, package design, and active/intelligent packaging technology for kimchi. From a packaging-material standpoint, although various materials have been used to ensure customer satisfaction and convenience, plastic is the most widely used material, in the form of bags, trays, pouches, and rigid containers. Additionally, recent efforts in the kimchi packaging industry have allowed companies to differentiate their products by using different packaging materials and technologies, while simultaneously improving product safety and quality. On the other hand, the biggest problem in kimchi packaging is excess $CO_2$ production, leading to package expansion and leakage. To alleviate this problem, the use of $CO_2$ absorbers, high $CO_2$-permeable films, and degassing valves, in addition to the use of different packaging systems, has been investigated. Active and/or intelligent packaging systems have been developed, to include active functions beyond simply inert, passive containment and protection of the kimchi product. However, most such approaches are not yet adequately effective to be useful on a commercial scale. Therefore, further studies are needed to resolve the limitations of each technology.

The present study aimed to investigate the membrane stabilizing effect of Thymoquinone (TQ) on cell surface glycoconjugates and cytokeratin expression against DMBA induced hamster buccal pouch carcinogenesis. 0.5% DMBA painting (three times per week) in hamster buccal pouches for 14 weeks resulted in the formation of well developed oral squamous cell carcinoma. We observed 100% tumor formation with marked abnormalities of glycoconjugates status in tumor bearing hamsters as compared to control animals. Oral administration of TQ at a dose of 30 mg/kg body weight, to DMBA painted hamsters on alternate days for 14 weeks, reduced the tumor formation as well as protected the levels of cell surface glycoconjugates in DMBA painted hamsters. The present study thus suggests that TQ has potent chemopreventive efficacy as well as protected the abnormalities on cell surface glycoconjugates during DMBA induced hamster buccal pouch carcinogenesis.

In the embryo, the thymus originates from the third and fourth pharyngeal pouches and migrates from the superior neck to the mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue, and is caused by the aberrant migration of the embryonic thymus. Our patient was a 30-year-old woman who had a nodular lesion in the neck for several years. Ultrasonography and computed tomography were performed. She underwent surgery, and a histological examination resulted in a diagnosis of type AB thymoma. Herein, we report a case of ECT that was resected through a transcervical approach.

The DiGeorge syndrome is a rare congenital abnormality consisting of aplasia or hypoplasia of the thymus and parathyroid glands resulting from malformation of the third and fourth pharyngeal pouches. This syndrome usually includes congenital cardiac anomalies and abnormal facial features. We experienced a case of congenital cardiac anomaly associated with DiGeorge syndrome. The patient was 1 month old boy weighing 3.5 kg. The congenital cardiac anomalies included ventricular septal defect, atrial septal defect, coactation of aorta, and patent ductus arteriosus. We performed one-stage operation with two separate incisions for these cardiac anomalies. Postoperative course was uneventful and the patient at 6 months of follow up is doing well.

Epiploic appendages are small, 0.5-5 cm long, peritoneal pouches containing small vessels and fat, located on the serous surface of the colon, from the cecum to the rectosigmoid junction. Pathologic states are rare in these appendages, the most frequent being is infarction either due to torsion or spontaneous. As a result of subsequent inflammatory reaction, the condition has been termed primary epiploic appendagitis. The condition is manifested by localized abdominal pain, which is often mistaken for appendicitis or diverticulitis and is usually diagnosed at surgery. With the aid of comtemporary imaging modalities, however, the diagnosis of epiploic appendagitis need no longer hinge on the pathologic specimen but may be established by the clinician. As this disorder recently has been demonstrated to be predominantly self-limited, laparotomy is no longer considered necessary. Conservative management has been shown to be safe. We report a 5-year-old male patient with epiploic appendagitis who presented with acute abdominal pain.
