Fruits with antioxidant enrichment can be an economically affordable supplement for mitigating oxidative damage prone spermatozoa membrane pathologies. Computer-assisted sperm analyzer and oxidative status were utilized to evaluate the impact of watermelon (Citrullus lanatus) fortification of dextrose saline as diluent for rooster semen and fertility response of hens inseminated. Watermelon juice and dextrose saline were used to formulate diluent of 7 treatments consisting of unextended semen (positive control), 10%, 20%, 30%, 40%, 50% and only dextrose saline (negative control) designated as Treatments 1-7. Pooled semen was obtained from fertile roosters and equilibrated with diluents at ratio 1:2 in the various treatments and were evaluated using computer software coupled microscope and seminal oxidative status assay. 168 laying hens randomly divided into 7 treatment of 8 replicates and 3 hen per replicate. Hen were everted, and semen (2 × 108 Spermatozoa) deposited intra-vagina and eggs collected over 8 weeks to assess fertility and hatchability of eggs laid. The result obtained revealed that watermelon-dextrose saline rooster semen diluent enhanced progressive motility, sperm kinetics and lowered non-progressive motility in T2-T6 compared to T7 over the 3 hours of evaluation. Watermelon addition to rooster semen diluent enhance the antioxidant capacity of rooster semen and lowered lipid peroxide generation. The percentage fertility was highest in T3 (81.01%) and T4 (81.24%) with lowest value obtained in T7 (73.46%). The hatchability of eggs set of hens inseminated with undiluted semen (71.46%) was lower than values for hens inseminated with watermelon inclusive extended semen (75.71%-80.39%). The optimal inclusion of 30%-40% watermelon in dextrose saline diluent enhance rooster semen kinetics, seminal oxidative stability and egg fertility.

Purpose: The aim of this study was to compare the potency-stabilizing effects of two different diluents of botulinum toxin A (10% dextrose solution and 0.9% saline). Methods: A mouse lethality bioassay was undertaken. Ninety mice were divided into experimental and control groups which received varying dosages in subgroups of 10. The experimental group was injected with botulinum toxin A diluted with 10% dextrose solution and the control group was injected with botulinum toxin A diluted with 0.9% saline. A 72 hours after intraperitoneal injection, the number of dead mice was counted to confirm median lethal dose ($LD_{50}$) of each group. Results: The value of $LD_{50}$ in the experimental group was approximately 0.131 mL (1.31 U) and the value of $LD_{50}$ in the control group was approximately 0.107 mL (1.07 U). The potency preservation rate of the experimental group was estimated to be 93.5% and that of the control group was estimated to be 76.3%. Conclusions: Dilution with 10% dextrose solution displayed less potency loss than 0.9% saline.

The stability of ondansetron and fluconazole in 5% dextrose injection and normal saline during simulated Y-site injection at room temperature was studied. Ondansetron 0.03, 0.1 and 0.3 mg/ml were admixed 1:1 with fluconazole 2 mg/ml. The solutions were stored at room temperature and samples were retrieved at time 0, 1, 2, 4 and 12 hr for immediate assay. At the time of the assay and before any dilution, each sample was visually inspected for clarity, color, precipitation, and the pH was determined. Drug concentrations were measured by a stability-indicating high performance liquid chromatograph. Ondansetron 0.03, 0.1 and 0.3 mg/ml were stable when mixed with concentration of fluconazole 2 mg/ml. There were no change in clarity and color and no precipitates in any admixture for 12 hr of inspection. The pH measurements did not have a particular trend in any direction over time.

Background: The study aimed to evaluate the effect of prehydration solution on hearing thresholds after cisplatin chemotherapy. Methods: In this retrospective cohort study, we reviewed the data of patients who underwent ≥3 courses of cisplatin-based chemotherapy for locally advanced head and neck cancers at a tertiary referral center (n=64). The dextrose solution (DW) group (n=26) received 2 L of normal saline and 1 L of 5% dextrose. The Hartmann solution (HS) group (n=38) received 2 L of normal saline and 1 L of HS. Hearing data were measured 1 day before starting the first course of chemotherapy, and again 20 days after the first, second, and third courses of chemotherapy. The severity of hearing loss was evaluated using the Common Terminology Criteria for Adverse Events (CTCAE). Results: Thresholds at all frequencies after chemotherapy were greater in the DW group than in the HS group. The increase in thresholds in 1 to 4 kHz after the third course of chemotherapy was greater in the DW group than in the HS group. CTCAE grades after the second and third courses of chemotherapy were greater in the DW group than in the HS group. Logistic regression showed that the odds ratio for CTCAE grade 3 or 4 after the third course of chemotherapy in the DW group was 4.84 on univariate analysis. Conclusion: Prehydration using a solution with salt was associated with a decrease in change in hearing thresholds after cisplatin chemotherapy in patients with head and neck cancers.

The study was undertaken to obtain indirect values of volume of packed red cell (VPRC) without centrifugation, using the erythrocyte sedimentation rate (ESR) of diluted blood in dogs. ESRs of diluted blood using the diluent of autologous plasma in which formed numerous RBC-rouleau clumps, autologous serum in which formed a few RBC-rouleau clumps, and 5% dextrose or 6% sucrose solutions in which formed numerous RBC-aggregation clumps, were accelerated. But, ESR of diluted blood using the 0.9% saline, D-S, ACD-B, CDP or D-PBS solutions were sluggish, because erythrocytes were dispersed in these diluents. Reliable values of VPRC on the basis of the correlating regressive equation to the ESR could be derived from values of$60^{\circ}$-angled-micro-ESR/40 min in the mixture, four parts of 5% dextrose solution and one part of whole blood. In the ESR values of diluted blood with low ratio, 1:1~3:1, $60^{\circ}$-micro-ESR was higher than $60^{\circ}$-Wintrobe-ESR. But, in the diluted blood with high ratio, 4:1~5:1, there was no different ESR values. For an aid of practical use, authers suggested a list of the $60^{\circ}$-micro-ESR/40 min in the diluted blood with equivalent VPRC of whole blood.

This study was undertaken to investigate the effect of the acidosis on the gastric acid secretion in the isolated whole stomach of the rat and the effect of prostaglandin $E_1$ on the gastric acid secretion influenced by the acidosis. Twenty-two male albino rats(Sprague-Dawley strain) were used. The isolated whole stomach from each rat was introduced into the Kreb's solution which was continuously gassed with $95%O_2-5%CO_2$ for 1 hour, after irrigation of the lumen with cold physiological saline$(4^{\circ}C)$. Thereafter, each stomach was irrigated again with 5% dextrose solution (pH 7.4, $37^{\circ}C$), and filled with the dextrose solution. All the stomachs with the dextrose solution were divided into 4 groups according to the Kreb's solutions in which each stomach was incubated for 30 min: 1) control group, in the pH 7.4 solution, 2) $PGE_1$ group, in the pH 7.4 solution containing $5\;{\mu}g/ml$ of $PGE_1$, 3) acid group, in the pH 7.0 solution, and 4) $acid+PGE_1$ group, in the pH 7.0 solution containing $5\;{\mu}g/ml$ of $PGE_1$. After incubatory period, the contents of each stomach were collected and centrifuged(1,500 rpm, room temperature) for 15 min. The acid output in the supernatant was determined with 0.012 N NaOH by means of autotitrator(Dosimat, Metrohm Herisau Co.) at pH 7.4. Results obtained were as follows: 1) The acid output of the acid group increased significantly in comparison with the control value. 2) The acid output of the $acid+PGE_1$ group decreased significantly in comparison with the acid group. It is inferred from the above results that the acidosis facilitates the gastric acid secretion and $PGE_1$ inhibits the gastric acid secretion induced by the acidosis.

Paraquat, one of the potent herbicides, causes fatal damage to many vital organs, when orally ingested, resulting in circulatory failure, respiratory distress syndrome, and a few other serious problems, but there is no known specific antidote against it. Of the possible problems related to paraquat intoxication, oliguric acute renal failure, which has been known to develop within 24 or 48 hours after intoxication, are notoriously life-threatening. So we attempted to investigate the clinical characteristics and progress of paraquat-induced acute renal failure and the therapeutic possibilities of herbal medicines. All of the fifteen subjects were treated with intravenous fluid injection of 5% dextrose saline or 10% dextrose water in conjunction with herbal medicines which were used for oral administration or gargling. Gamdutang, a decoction of Semen Glycin(黑豆 200g) and Radix Glycyrrhizae(甘草 100g) with addition of other herbs when necessary, was administered orally. At the same time, gargling fluid, consisted of Chinese ink(墨汁), char-frying powder of Rhei Rhizoma(大黃炒炭末), Succus phyllostachyos(竹瀝), was used to detoxify the oral cavity. Serum levels of Blood Urea Nitrogen(BUN) and Creatinine reached its peak on the third day of hospitalization, but then decreased and fell within the normal range on the 7th day and remained there. Serum levels of Na+ and K+ decreased down below the lower limits of normal range on the 7th day and on the 3rd day, respectively. Then they returned back within normal limits. Mean urine output on the 1st day of hospitalization was 1,050ml and it continuously increased to reach more than 2,000ml on the 14th day. From that day on, it stayed over 2,000ml. Fifteen cases of acute renal failure caused by paraquat intoxication were treated with combined treatments of oriental and western medicine in our hospital. However, we think that it is necessary to study further about the way to combine oriental and western medicine, to find out a more effective treatment method.

Paclitaxel is an effective antineoplastic agent against ovarian, colon and breast tumors. But there have been many difficulties to formulate this drug due to the extremely low aqueous solubility. Paclitaxel is currently formulated in a vehicle composed of Cremophor EL and absolute ethanol mixture which is $5\~20$ fold diluted in normal saline or $5\%$ dextrose solution before I.V. injection. However, this formulation has many problems such as allergic reactions and drug precipitation on aqueous dilution. To overcome these problems, we prepared the micelle and microemulsion systems for parenteral administration of paclitaxel by using glycofurol, $Soluto^{(R)}lHS$ 15 and oleic acid. Phase diagram, pH-rate stability, particle size distributions and pharmacokinetics of the systems were studied. Micelles and microemulsions formulated as nano-particle delivery system were physically and chemically stable. Therefore, these formulations might be the promising alternative candidate for the parenteral delivery of paclitaxel.

Clinical experience on 16 cases of open heart surgery under the extracorporeal circulation with mild or moderate hypothermia and partial hemodilution technique at the National Medical Center during the period from June 1976 to October 1977. Nine of sixteen were congenital heart disease and seven were acquired heart disease. The age of the patient ranged between 6 and 48 years. The body weight varied from 18.5kg to 60kg and body surface area 0. 79-1.70m2. The average priming volume of pump oxygenator was 2080 ml, which was consisted fresh ACD blood, buffered Hartmann`s solution, Mannitol, 50% dextrose in water and Vit. C. The average hemodilution rate was 27%. The average flow 2.3 L/min/m2 or 80 ml/min and the duration of perfusion varied from 31 min to 270 min with average of 107 min. The perfusion was carried out under the mild or moderate hypothermia using core cooling alone in 10 cases, core cooling and local myocardial cooling with $0-4^{\circ}C$ physiologic saline in 2 cases. From a hemodynamic point of view, the blood pressure dropped down around 80 mmHg after the initiation of perfusion follwed by increase to safety level and stable during the perfusion. The central venous pressure remained within normal limits. In most cases, hemoglobin and hematocrit decreased during and after the perfusion. Hemogiobin level was decreased, average of 20.6 %, hematocrit 18.6%, pletelets 55% postoperatively. Plasma hemoglobin increased moderately, from preperfusion average valve of 7.79 mg % to post-perfusion value of 54.7 mg %. Electrolytes changes during cardiopulmonary bypass showed definite hypokalemia but changes of Na, Ca were not definite. Arterial blood gas analysis during cardiopulmonary bypass suggested that the metabolic acidosis which was accompanied by respiratory alkalosis which was corrected postoperatively. As the opera tive complication, transient hemoglobinuria in 4 cases and neurological signs in 2 cases were all cured. There were 2 death cases and operative mortality rate was 12.5%.
