  • This prospective study aimed to assess the efficacy of dexamethasone to prevent xylazine induced emesis in dogs. The antiemetic effect of graded, single high-dose intravenous dexamethasone against xylazine hydrochloride was studied. Clinically healthy mixed breed dogs that weighed $ 4.64\pm1.25kg$ were used in this study. Food and water were given 3 hours before the experiment. Venous blood specimens were collected from all experimental animals for hema-tological and blood chemical test pre- and post-experiment. Twenty-eight experimental animals were randomly divided into 4 groups; the group treated with 0.2ml/kg of normal saline (Control group), the groups treated with 1mg/kg (D1 group), 2mg/kg (D2 group) and 4 mg/kg of dexamethasone (D4 group). Three doses of the dexamethasone or normal saline was administered intravenousely to each group and after 5 minutes, xylazine (2.2 mg/kg) was administered intramuscularly. The time until onset of the first emetic episode and rate of emesis were investigated. At the same time, the extent of sedation was scored subjectively 5, 15, 30 and 60 minutes after injection of xylazine hydrochloride using Visual Sedation Score. The time until onset of the first emetic episode was $203.25\pm11.35$ sec in Control group, $187.33\pm48.0l$ sec in D1 group and 218.33± 13.58 sec in D2 group. The rate of xylazine induced emesis were $57\%$ in Control group and $43\%$ in D1 and D2 group respectively. On the other hand, any emetic episodes were not observed in 04 group. At extent of sedation score, all experimental animals especially including the animals in D1 group were highly sedated at 15 minutes after administration of xylazine hydrochloride. Hematological and blood chemical values showed normal ranges pre- and post-experiment. We concluded that prior treatment with 4 mg/kg of dexamethasone hardly caused xylazine-induced emesis without disturbing the sedative effect of xylazine in dogs.

  • The present study was made in order to clarify the anti-emetic effect by needle-acupuncture (AP), injection-AP and moxibustion in xylazine - induced vomiting of dogs. Twelve mongrel dogs (4 months to 5 year old, 2 to 4 kg of body weight), eleven mongrel dogs (4 months to 5 years old, 2 to 10 kg of body weight) and twelve mongrel dogs (4 months to 1 year old, 2 to 4 kg of body weight) were used for clarification of anti-emetic effect by needle-AP, injection-AP and moxibustion, respectively. The experimental animals were devided into control(6 heads), BL-21(6 heads), CV-12(6 heads) and BL-21+CV-12(6 heads) groups using total 6 dogs with vomiting selected in preliminary experiment, respectively in needle-AP treatment. In addition, the experimental dogs were divided into control (11 heads), BL-21 (6 heads) and CV-12(6 heads) groups using 11 dogs, respectively in injection-AP treatment. In moxibustion treatment the experimental dogs were divided into control (6 heads), BL-21(6 heads) and CV-12(6 heads) groups using 6 dogs, respectively. Five days after the experiment of one group was finished, the other group was examined in each experiment. Acupuncture needle was maintained for 20 minutes in needle-AP treatment. Metoclopramide was used in injection-AP treatment. Commercial moxa was used in moxibustion treatment. Vomiting was induced by intramuscular injection with $2{\%}$ xylazine 20 minutes after treatments of needle-AP, injection-AP and moxibustion, respectively. The vomiting rates of BL-21($33.3{\%}$), CV-12($50{\%}$) and BL-21+CV-12($33.3{\%}$) were lower than that of control($66.7{\%}$) and vomiting times of experimental groups were similar to that of control in needle-AP treatment. The vomiting rates of BL-21 ($0{\%}$) and CV-12($16.4{\%}$) were lower than that of control($66.7{\%}$) and the vomiting time of CV-12 group was similar to that of control group in injection-AP treatment. The vomiting rates of BL-21($33.3{\%}$) and CV-12($33.3{\%}$) were lower than that of control ($66.7{\%}$) and vomiting times of experimental group were similar to that of control group in moxibustion treatment. In conclusion, it was considered that needle-AP, metoclopramide injection-AP and moxibustion at BL-21 and CV-12 were effective for anti-emesis in xylazine induced vomiting of dogs and metoclopramide injection-AP was the most effective method for anti-emesis among them.

  • Bacillus cereus is a gram-positive spore-forming bacterium and produces an emetic or diarrheal syndrome induced by an emetic toxin and an enterotoxin, respectively. In this study, the effect of different types of media, temperature, and time on the sporulation of B. cereus, and thermal resistance of B. cereus spores produced in various temperatures were evaluated. The highest levels of spores were detected when they are produced at $25^{\circ}C$. There were no significant differences in levels of spores produced at $25^{\circ}C$ among culture media and times while levels of spores produced at $43^{\circ}C$ were significantly reduced with the increase of time. However, thermal resistance of B. cereus spores could be affected by incubation temperature. In fact, higher D-values (12.0, 10.1, and 5.9 min for 2,4, and 6 weeks, respectively) of spores produced at $43^{\circ}C$ were observed than did in samples produced at other temperatures (25 and $37^{\circ}C$). D-values of spores were 7.7, 8.2, and 12.0 min when they were produced at 25,37, and $43^{\circ}C$ for 2 weeks, respectively. The sporulation of B. cereus at $25^{\circ}C$ could result in high amounts of spores however the sporulation at $43^{\circ}C$ for 2 weeks could be effective to produce thermal resistant spores.

  • Two-hundred Bacillus cereus isolated from perilla leaf cultivation areas in Miryang, Korea were investigated for toxin genes and antibiotic susceptibility. Toxigenic patterns of isolates were identified to be 11 groups through toxin gene profiles. 21% of strains isolated from the perilla leaves had both enterotoxin and emetic toxin. Toxin genes entFM (100%), nheA (100%) and hblA, C, D (65.5%) were frequently found in the perilla leaves, whereas EM (21.0%) was less common. Most isolates were susceptible to 10 antibiotics, but they were highly resistant to penicillin (100%), ampicillin (100%), oxacillin (94.9%), amoxicillin-clavulanic acid (95.6%), cefazolin (78.2%), and rifampicin (58.0%). These results indicate that food-borne outbreak caused by B. cereus might lead to diarrhea and emetic syndromes.

  • Objectives: This study aimed to investigate the effect of banhasasim-tang intravenous herbal acupuncture (BST-IVHA) on emesis induced by chemotherapy in rats. Methods: This study used methotrexate(MTX)-induced Rat-Pica model. The rats were randomly allocated into seven groups; normal group, two saline groups, four Banhasasim-tang(BST) groups (groups treated with BST-IVHA). All the experimental animals except those in the normal group were injected with MTX. Those in the pre-treatment groups were treated with saline injection (saline group) or BST-IVHA (BST group) before MTX injection. Those in the post-treatment groups were treated with saline injection or BST-IVHA after MTX injection. Two different dosages of BST-IVHA solution (low dose; BST-1 group, high dose; BST-2 group) were used. The changes in body weight, food intake, and kaolin consumption at 24h, 48h, and 60h were monitored and analyzed. Results: 1. No significant change was found in body weight. 2. The food intake at 48h was increased significantly in the BST-1 pre-treatment group($19.89{\pm}0.01g$) compared to the pre-saline group($18.68{\pm}0.26g$). 3. The kaolin consumption was significantly decreased in the BST-1 pre-treatment group at 24h($0.24{\pm}0.02g$) and 60h($0.36{\pm}0.14g$), in the BST-2 pre-treatment group at 48h($0.02{\pm}0.01g$) and 60h($0.80{\pm}0.31g$) compared to the pre-saline group($24h:0.81{\pm}0.37g$, $48h:0.76{\pm}0.43g$, $60h:1.56{\pm}0.03g$). The kaolin consumption was also significantly decreased in the in the BST-1 post-treatment group at 24h($0.05{\pm}0.02g$), 48h($0.64{\pm}0.06g$) and 60h($0.14{\pm}0.05g$), in the BST-2 post-treatment group at 48h($0.01{\pm}0.01g$) and 60h($0.01{\pm}0.01g$) compared to the post-saline group($24h:0.51{\pm}0.4g$, $48h:3.58{\pm}0.33g$, $60h:2.5{\pm}0.2g$). Conclusions: BST-IVHA showed an anti-emetic effect in MTX-induced rat-pica model. This result suggests that BST-IVHA could be an effective treatment for chemotherapy-induced emesis.

  • Bacillus cereus is a gram-positive, rod-shaped, spore-forming bacterium that has been isolated from contaminated fermented soybean food products and from the environment. B. cereus produces diarrheal and emetic toxins and has caused many outbreaks of foodborne diseases. In this study, we investigated whether B. amyloliquefaciens RD7-7, isolated from rice doenjang (Korean fermented soybean paste), a traditional Korean fermented soybean food, shows antimicrobial activity against B. cereus and regulates its toxin gene expression. B. amyloliquefaciens RD7-7 exhibited strong antibacterial activity against B. cereus and inhibited the expression of B. cereus toxin-related genes (groEL, nheA, nheC, and entFM). We also found that addition of water extracts of soybean and buckwheat soksungjang (Korean fermented soybean paste made in a short time) fermented with B. amyloliquefaciens RD7-7 significantly reduced the growth and toxin expression of B. cereus. These results indicate that B. amyloliquefaciens RD7-7 could be used to control B. cereus growth and toxin production in the fermented soybean food industry. Our findings also provide a basis for the development of candidate biological control agents against B. cereus to improve the safety of fermented soybean food products.

  • Objective : "Dochangbup" is one of the therapies that remove pathogenic qi[邪氣] from the Emetic Method in the Miscellaneous Disorders part of Dongeuibogam東醫寶鑑. It is, in particular, the method of treatment that removes phlegm[痰], the cause of various disorders. Method : Application of "Dochangbup" had a long history in Korea as well. The meaning and application of "Dochangbup" are mentioned in various texts from early Chosun dynasty to the post liberation. Result : In China, there are a lot of medical texts by physicians throughout Ming and Qing Dynasty, with GeZhiYuLun格致餘論 at the top of the list, dealing with the meaning and applicable scope of "Dochang" method and pharmacy of "Hacheongo霞天膏". Most of the physicians are affiliated with Dan Xi School, regarding ZhudanXi朱丹溪 as a suzerain. In "Dongeuibogam", it is mentioned that "Dochangbup" can treat various disorders caused by phlegm. Though, when there is a possibility of harming original qi[元氣] during the treatment or grave deficiency in patients, it is requested to consider tonifying while purging. Conclusion : "Dochangbup" can be applied not only to the disorders mentioned in classical medical texts, like heart pain[心痛], leg disease[脚氣], urine turbidity[小便濁], involuntary discharge of semen[遺精], cough[咳嗽], blood spitting[喀血], but also to metabolic syndrome such as obesity, hypertention and diabetes, commonly found in the modern era.

  • The supportive care of patients receiving antineoplastic treatment has dramatically improved over the past few years and development of effective measures to prevent nausea and vomiting after chemotherapy serves as one of the most important examples of this progress. A patient who starts cancer treatment with chemotherapy lists chemotherapy-induced nausea and vomiting as among their greatest fears. Inadequately controlled emesis impairs functional activity and quality of life, increases the use of health care resources, and may occasionally compromise adherence to treatment. New insights into the pathophysiology of chemotherapy-induced nausea and vomiting, a better understanding of the risk factors for these effects, and the availability of new antiemetic agents have all contributed to substantial improvements in emetic control. This review focuses on current understanding of chemotherapy-induced nausea and vomiting and the status of pharmacological interventions for their prevention and treatment.

  • 'Gunja' is attributable to the plant Abrus precatorius L. (Leguminosae). Three forms with red, brown and another with white seeds are known to occur in this species and are employed for different therapeutic uses viz. as purgative, emetic, aphrodisiac, tonic and also as an abortifacient. According to some Ayurvedic literature the seeds are poisonous and should be given to the patients after proper processing ('Shodhan'). A comparative study of various phytochemical parameters, namely, percentage of successive extractives, total proteins, tannins, total ash and acid insoluble ash of these three forms of the processed (with cow's milk and Kanji) and unprocessed seeds was done. TLC and densitometric scanning of successive extractives was also carried out to serve as markers for processed and unprocessed seeds. The percentage of proteins, tannins, alcohol and water soluble extractives decreased in the processed material. Besides, their acute toxicity, CNS activity were also studied in albino mice and it was found that white seeds are more toxic as compared to the red and brown. The toxic effect was reduced with the processing. Further, the 'Kanji' processed seeds are less toxic than the milk processed one.
