  • Purpose : Some patients develop side effects from theophylline even at low serum concentrations. We designed a prospective study to evaluate the side effects of theophylline. Methods : A Prospective, controlled trial study was conducted. The low-dose group received an intravenous continuous aminophylline dose of 5 mg/kg/day on the first day and subsequently 10 mg/kg/day on the following two days. The usual-dose group received 10 mg/kg/day for three days and the control group received normal saline for three days. Heart rate, respiratory rate, serum concentration of theophylline, and four adverse events (irritability, sleep disturbance, jitter, and vomiting) were checked at the time of admission and at 2, 12, 24, 48, and 72 h after the start of aminophylline infusions. Results : Nine patients out of 37 in the low-dose group and six of 21 in the usual-dose group dropped out because of uncontrolled irritability. The serum concentrations of theophylline in dropouts ($3.68{\pm}1.93$ ig/mL) and participants ($4.47{\pm}2.45$ ig/mL) were not significantly different. Irritability was a more frequent side effect in the usual-dose group at 12 h, but there was no difference between the low-dose and usual-dose groups in terms of vomiting, sleep disturbance, and jitter. Most of the severe adverse effects were observed in children below two years of age. Conclusion : Some patients dropped out regardless of the initiating aminophylline dose, especially patients under the age of two years.

  • Various health benefits of turmeric have been reported. Therefore, an innovative application of turmeric as a functional food was explored. In the current study, effects of an extrusion process on the chemical properties and antioxidant activities of turmeric were investigated. Extrusion of turmeric was performed at $150^{\circ}C$ using screw revolution speeds of 500, 1,000, 1,300, and 1,600 rpm. A significant reduction in turmeric pigments and the formation of browning compounds occurred due to the extrusion. The degradation of pigments was proportional to the increase in screw speed. Infusion yields were significantly increased after the extrusion. The content of proteins and polyphenols, as well as the content of flavonoids in infusions and EtOH extracts were significantly reduced by the extrusion. Scavenging activities of turmeric against DPPH and ABTS radicals were also significantly reduced following the extrusion. These results indicate that the extrusion process caused a significant loss of pigments and decreased the antioxidant activities of turmeric. Therefore, further study related to the development of a proper extrusion process is to be needed.

  • Research was carried out to ascertain whether or not the volume of saliva flowing into the rumen regulates dry forage intake in ruminants. Goats with a parotid fistula were fed roughly crushed alfalfa hay cubes, concentrated beef cattle feed and $NaHCO_3$ wice daily (10:00-12:00, 16:00-18:00). Except for the days on which experiments were conducted, the animals were free access to drinking water. The animals were intraruminally infused every day prior to the morning feeding period with parotid saliva collected from the parotid fistula over a 24 h period. The present experiment consisted of three treatments, non-infusion (NI), intraruminal infusion of parotid saliva (RSI), and intraruminal infusion of warm water (RWI). In the RSI treatment, approximately 4-5 kg of parotid saliva (280-290 mOsm/l) collected over a 24 h period was intraruminally infused 1 h prior to the commencement of morning feeding. In the RWI treatment, parotid saliva was substituted for warm water ($36^{\circ}C$). After infusions, the animals were fed on roughly crushed alfalfa hay cubes for 2 h. During feeding, eating and saliva secretion rates were measured. Blood samples were also periodically collected from the jugular vein. After 2 h feeding, water intake was measured for 30 min. These measurements were used to define thirst levels. On the day of the experiment, the animals were not access to drinking water during the morning feeding. It is thought that rumen fill in RSI and RWI treatments was higher than the NI treatment. In comparison with the NI treatment however, cumulative feed intake increased by 39.3% with RSI treatment and by 45.9% with RWI treatment after completion of the 2 h feeding period. After 2 h feeding, thirst level in the RSI treatment showed only a 10% decrease compared to the NI treatment, but thirst level in the RWI treatment decreased 49.8%. Despite the significant differences in thirst levels between RSI and RWI treatments, the cumulative feed intake in both treatments was similar. When comparing accumulated saliva secretion volumes 2 h after feeding, volumes in the RSI treatment were significantly 35.9% lower than the NI treatment while volumes in the RWI treatment were unchanged. However, the volumes of saliva and fluid flowing into the rumen were greater in both RSI and RWI treatments when compared to the NI treatment. The results indicate that the amount of saliva flowing into the rumen is a factor regulating feed intake in ruminants fed on dry forage.

  • In this study, to evaluate the anti-obesity effects of mulberry leaf tea and its fermented product by Monascus pilosus, we investigated body and organ weight, blood and liver biomarkers in mice fed 1% tea infusions instead of water for 8 weeks. Mice were divided into three groups such as a normal control (NC), unfermented mulberry leaf tea infusion (UMI) and fermented mulberry leaf tea infusion (FMI). Although it is not significant, tea infusion groups showed reduction of body weight gains compared with NC group. Moreover, contents of LDL-cholesterol and lipid peroxide (LPO), altherogenic index, and xanthin oxidase (XO) activity were significantly decreased, and glutathione S-transferase (GST) activity was significantly elevated. The results from this study suggested that UMI and FMI may have an anti-obesity activity, upregulate antioxidant enzymes and reduce levels of oxidants related to liver damage.

  • A study was carried out to assess the therapeutic effect of ascorbic acid in mastitis of dairy cows. The herd with a population of 250-275 lactating cows was screened for clinical and subclinical mastitis for a period of 5 months. Based on inclusion and exclusion criteria, eighteen animals each with clinical and subclinical mastitis in one quarter only were selected as study population. Twelve cows (group A) with normal udder and health were also selected as a healthy control. Clinical mastitis cows were grouped as B (n=12) and C (n=6). Cows of group B were treated with ascorbic acid at 25 mg/kg, subcutaneously for 5 consecutive days and intramammary infusion (Ampicillin sodium 75 mg and Cloxacillin sodium 200 mg/infusion) based on antibiotic sensitivity test, till complete recovery. Group C cows received only intramammary infusion till the complete recovery. Eighteen subclinical mastitis cows were divided in group D (n=12) and E (n=6). Cows of group D were treated with ascorbic acid at 25 mg/kg subcutaneously for 5 consecutive days while group E did not receive any treatment. California mastitis test (CMT), somatic cell count (SCC), physical changes of udder and milk were used to diagnose and classify the mastitis. Evaluation of the therapy was based on CMT score and physical changes of udder and milk. Sample size calculation was also performed but was not followed for control groups due to scarcity of cases. Adequate blinding was done when and where required to avoid the biases. Confounding variables like herd, age of the cow, stage of the lactation, season and geographical region were duly considered and adequate blocking was followed. Ascorbic acid was administered in clinical and subclinical cases even after cure considering its immunostimulatory and healing inducing effects. The recovery rate was faster in cases of clinical mastitis treated with ascorbic acid along with an intramammary infusion (group B) than the quarters of group C cows. Quarter wise the average duration/number (3.16${\pm}$0.11 days) of antimicrobial intramammary infusion was significantly (p<0.01) less in group B than that of average duration/number (5.33${\pm}$0.20 days) of group C. Subclinical mastitis cows treated with ascorbic acid showed 83.33% recovery while 16.77% did not respond to treatment till last day of study. Cows of group E (untreated) did not recovered from the mastitis. Subjective parameters viz. swelling, pain reflex of udder and physical changes in milk from quarter of ascorbic acid treated cows (group B) disappeared earlier than that of group C cows. It is concluded from this study that the ascorbic acid might be useful as an adjunct in case of clinical mastitis to get quick recovery with less number of intramammary infusions. High recovery rate in subclinical mastitis quarters of group D cows is appreciable and opens a new avenue to conduct further trials in a larger population in various field conditions. However, the pharmacology of ascorbic acid with particular reference to health of mammary gland needs to be investigated.

  • Pompe disease is a genetic disorder caused by a deficiency of acid ${\alpha}$-glucosidase (GAA). Infantile onset Pompe disease is uniformly lethal. Affected infants generally present in the first few months of life with hypotonia, generalized muscle weakness, and a hypertrophic cardiomyopathy, which is rapidly followed by death, usually by the age of one. The late-onset form is characterized less severe symptoms and prognosis. Therapy for Pompe disease is intended to directly address the underlying metabolic defect via intravenous infusions of recombinant human GAA to replace the missing enzyme. We report a case of atypical infantile-onset Pompe disease that presented symptoms in infancy but had less severe clinical manifestations and improved after GAA enzyme replacement ($Myozyme^{(R)}$, Genzyme Co., MA, USA) therapy. It is very important that pediatricians become aware of signs and symptoms of Pompe disease, such as a nasal voice or a waddling gait at an early stage so that these patients can benefit from appropriate GAA replacement therapy as soon as possible.

  • This study prepares dried sweet pumpkins to optimize pretreatment conditions of blanching, steaming and microwave heating and to investigate the quality characteristic of each method. The sweet pumpkin blanching treatment of moisture content decreased gradually with increasing temperature, and soluble solids, and weight loss was increased. Color temperature is lower, and a higher value of L value and b value increased. As for the sweet pumpkin steaming treatment of moisture content, it was observed that the longer the steaming time was decreased, sugar content was increased. Change of color in the L value, the longer the steaming time a and b values. Also, as for the microwave treatment of the sweet pumpkin, the longer the time the moisture content decreased, it slightly increased soluble solids and weight loss. Blanching showed the lowest hardness of texture, followed by steaming, and microwaves, in order. Penetration per 20 hours per type was determined by sensory evaluation of sugar, and sugar:fructose(1:2)ratio were higher in the composition.

  • In this study lactating female rabbits and strains of coliforms previously isolated from the cases of acute and chronic mastitis in dairy cattle were employed. The pathological changes were observed on the mastitis experimentally induced with the coliform strains and the mamary glands after infusions of E. coli suspension together with dexamethasone, dextran iron or transferrin were grossly and microscopically observed. From the results reported, the following points are concluded. In the bacterial suspension-infused groups by E. coli, K. pneumoniae and Ent. aerogenes, respectively, the affected quarters of udder showed grossly swelling, hyperemia, hemorrhage, focal necrosis and firmness. The microscopic findings of early stage of the mastitis were appearance of large numbers of heterophils in the glandular lumina and ducts accompanied by degeneration, necrosis and desquamation of epithelial cells and also infiltration of heterophils, hemorrhage and edema in the interstitial tissue and destruction of alveoli. Later, proliferation of fibroblasts, plasma cells, lymphocytes, eosinophils and macrophages appeared in the glandular tissue and with these cells necrotic foci of glandular tissue were surrounded by highly proliferated connective tissue. In addition, granulomatous inflammatory changes could be observed in the glandular tissue from the 7th day after infusion. The difference of the inflammatory response among the groups did not recognized. In the groups infused with dexamethasone and E. coli suspension the inflammatory response was slighter at the inflammatory change with alveolar destruction and hemorrhage was more rapid and severer than E. coli alone. Also in the groups infused with dextran iron and E. coli suspension the inflammatory change was more rapid and severer than E. coli alone and the histological changes were not recognized in the groups infused with dextran iron alone. Reaction of the iron staining was diffusely strong positive within the glandular alveolar lumina in the groups of dextran iron alone, hut was slightly positive toward epithelial cells in the groups of dextran iron and E. coli infusion. In the group infused with transferrin and E. coli suspension, the inflammatory response was tighter, but the peroxidase activity of the heterophils in the glandular lumina was more or less stronger than E. coli alone.

  • Microbial-fermented tea (MFT), which is made by microorganisms through fermentation, is a popular beverage in Asia, especially in the Yunnam province, China. In this study, changes of the chemical constituents and antioxidant activity during the manufacturing process of MFT were investigated. MFT were respectively prepared from fresh leaves of three different tea species (Yabukita, Daecha, and Korean wild cultivar) and a processed green tea (Korean wild cultivar). The color of the tea infusions gradually changed to red and yellow as a function of fermentation time. Total nitrogen and caffeine contents were not significantly changed. Whereas, the chlorophyll, tannin, and total catechins contents gradually decreased. Interestingly, the epicatechin and epigallocatechin contents increased up to 25 days of fermentation and then decreased. Change of the chemical constituents of all samples showed the same patterns. The antioxidant activity of MFT from Daecha and Yabukita slightly decreased as increasing fermentation time. However, the range over which the antioxidant activity of MFT from Korean wild cultivar and green tea were not changed. This research suggests that it may be possible to manufacturing possibility of MFT using Korean wild cultivar and processed green tea.
