Increased access to highly active antiretroviral therapy (HAART) has made the management of drug toxicities an increasingly crucial component of HIV. This study investigated the effects of adjuvant use of coconut oil and HAART on testicular morphology and seminal parameters in Sprague-Dawley rats. Twelve adult male Sprague-Dawley rats, weighing 153~169 g were distributed into four groups (A-D) and treated as follows: A served as control (distilled water); B (HAART cocktail-Zidovudine, Lamivudine and Nevirapine); C (HAART + Virgin coconut oil 10 mL/kg) and D (Virgin coconut oil 10 mL/kg). After 56 days of treatment, animals were killed and laparotomy to exercise the epididymis for seminal fluid analyses done whilst testicular tissues were processed for histo-morphometric studies. Result showed a significant decline in sperm motility (P < 0.05) and count (P < 0.0001) in HAART-treated animals while there was insignificant changes in other parameters in groups C and D except count that was reduced (P < 0.0001) when compared with controls. Histomorphological studies showed HAART caused disorders in seminiferous tubular architecture with significant (P < 0.01) decline in epithelial height closely mirrored by extensive reticulin framework and positive PAS cells. Adjuvant Virgin coconut oil + HAART resulted in significant decrease in seminiferous tubular diameter (P < 0.05), but other morphometric and histological parameters were similar to control or Virgin coconut oil alone (which showed normal histoarchitecture levels). While derangements in testicular and seminal fluid parameters occurred following HAART, adjuvant treatment with Virgin coconut oil restored the distortions emanating thereof.

본 연구는 12주간 대사증후군 중년 여성들의 코코넛 오일 섭취와 복합운동이 신체조성, 산화스트레스 및 혈압에 미치는 영향을 규명하고자 하였다. 측정항목은 체지방(체중, 체지방, BMI, WHR), 산화스트레스(MDA, SOD), 혈압(SBP, DBP)을 측정하였다. 그 결과, 체중과 체지방에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 감소하였다. BMI, WHR에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 감소하였다. MDA에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 감소하였다. SOD에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 증가하였다. 수축기 혈압에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 감소하였다. 이완기 혈압에 있어서 코코넛 오일, 복합운동 프로그램 참여 전에 비해 후에 유의하게 감소하였다. 결론적으로 대사증후군 중년 여성들에 있어서 코코넛 오일 섭취와 복합운동은 체지방, 산화스트레스, 혈압 관리에 효과적인 것으로 나타났다.

This current study investigated the anti-ulcer activity of 2 types of virgin coconut oil (VCO-A and VCO-B) and coconut oil (CO). Sprague-Dawley of male rats divided into 6 groups and each group consisted of ten rats. Rats were then treated with either VCO or CO and then were then anaesthetized and pyloric ligation was performed. The anaesthesia was discontinued and the animal usually recovered consciousness within less than an hour. Three hours later, the animal was then again anaesthetized and sacrificed with chloroform. Stomach removed and its content subjected to measurement of volume and pH. The results revealed VCO-B and VCO-A (100%) significantly inhibited (p < 0.001) the volume of gastric juice secreted by the control rats by 66.81% and 51.53%, respectively. Followed by CO 42.80%. While the inhibition of gastric juice for positive control rats which treated with ranitidine (100 mg/kg) was only 22.38%. The total acid output was reduced by the oils to 70.80%, 74.16% and 40.45% for VCO-A, VCO-B and CO respectively compared to control group. Ranitidine reduced the total acid output by 34.83%. In conclusion, prevention of gastric lesions in rats by VCO was found to increase the mucous and decrease the acid volume, total acid contents and ulcer scoring. The treatment of VCO affects the all parameters that influence the initiation and perpetuation of ulceration.

The aimed of the presence study was to determine the antiulcer potential of virgin coconut oil (VCO), either extracted by wet process (VCO_A) or fermentation process (VCO_B), and to compare their effectiveness against the copra oil (CO) using the HCl/ethanol-induced gastric ulcer model. Earlier, the oils underwent chemical analysis to determine the free fatty acids composition, physicochemical properties and anti-oxidant capability. In the antiulcer study, rats (n=6) were pre-treated orally for 7 consecutive days with distilled water (vehicle), 100 mg/kg ranitidine (positive group) or the respective oils (10, 50, and 100% concentration). One hour after the last test solutions administration on Day 7^th, the animals were subjected to the gastric ulcer assay. Macroscopic and microscopic analyses were performed on the collected rat's stomachs. From the results obtained, the chemical analysis revealed i) the presence of high content of lauric acid followed by myristic acid and palmitic acid in all oils and; ii) the significant (^*p< 0.05) different in anisidine- and peroxide-value, percentage of free fatty acid, total phenolic content and total antioxidant activity among the oils. The animal study demonstrated that all oil possess significant (^*p< 0.05) antiulcer activity with VCO_B being the most effective oil followed by VCO_A and CO. The macroscopic observations were supported by the microscopic findings. Interestingly, all oils were more effective than 100 mg/kg ranitidine (reference drug). In conclusion, coconut oils exert remarkable antiulcer activity depending on their methods of extraction, possibly via the modulation of its antioxidant and anti-inflammatory activity.

본 연구를 통하여 P. aeruginosa PR3를 이용하여 DOD를 생산하기 위해 저가의 기질로서 필리핀 너트유가 효과적으로 사용될 수 있음을 확인하였으며 배지에 첨가되는 여러 영양인자들의 영향을 조사하여 DOD 생산성을 크게 향상시킬 가능성이 있음도 확인하였다. 따라서 DOD 생산에 이용되는 올레산을 식물성오일로부터 별도의 생산과정을 거쳐 생산하지 않고 식물성오일자체를 직접 기질로 사용함으로서 PR3 균주를 이용하여 고부가가치의 DOD를 효율적으로 생산할 수 있다는 것을 확인하였다.
