In vivo analyses of the effects of co-administration of Carica papaya leaf extract with ciprofloxacin
Carica papaya leaf extract is an antisickling phytomedicine reported to inhibit the polymerisation of defective hemoglobin S molecules in sickle cell individuals. In this research, the biochemical effects of ciprofloxacin, a wide spectrum antibiotic, co-administered with C. papaya leaf extract was studied. Using standard methods for biochemical, hematological and antioxidant assays, results showed that...

Formulation and evaluation of Cymbopogon citratus dried leaf-powder tablets
The objective of this study was to formulate Cymbopogon citratus leaves powder into tablets using both acacia and gelatin as binders at concentrations of 2, 4, 6 and 8% w/w, respectively. The tablets were evaluated using the necessary official and unofficial tests. The results showed that all the batches of tablets passed the uniformity of weight test. The hardness of the tablets was significantly affected by...

Effects of erythropoietin on methotrexate induced lung injury in rats
The aim of our study was to investigate the effect of erythropoietin on methotrexate induced lung injury in rats. Twenty-one female Sprague-Dawley rats were randomly assigned into 3 groups (n=7). Single-dose subcutaneous injections of 0.3 ml serum physiologic was administered to sham group, single-dose 20 mg/kg methotrexate was administered to the control group, and single-dose 20 mg/kg methotrexate and 5000 IU/kg...

Synthesis and characterization of hydrophobically modified chitosan
The aim of this paper was to prepare and evaluate the feasibility of hydrophobically modified chitosan for hemostatic use. Chitosan was grafted with different branched chains by schiff reaction with salicylaldehyde and dodecyl aldehyde and followed by reductive amination with NaBH4. Elemental analysis was carried out to calculate the degree of substitution (DS) for NH2. Fourier transform infrared spectroscopy (FTIR) and...

Cell division inhibitor minC from Lactobacillus Acidophilus VTCC-B-871 and detection of antimicrobial activities in functional study
The minC gene of Lactobacillus acidophilus VTCC-B-871 was identified based on the genome data of L. rhamnous strains in genebank, and antimicrobial activities other than cell division inhibitor was detected. After cloning and sequencing, there was 99.1% homology betweenminC gene of L. acidophilus VTCC-B-871 and L. rhamnous GG using...

Potentialization of antioxidant activity of Piper umbellata (Piperaceae) leaves after their metabolism in Heraclides brasiliensis larvae (Lepidoptera: Papilionidae)
Piper umbellata leaves accumulate the compound, 4-nerolidylcatechol, which is responsible for the antioxidant power of the plant. Surprisingly, in this study we observed a significant increase in the antioxidant activity of P. umbellata leaves after their metabolism on Heraclides brasiliensis larvae. The total phenolic concentrations of the extracts from the leaves and...

Carnosine and cyclosporine A alleviate brain damage after traumatic brain injury in rats
The present study investigates the effects of carnosine and/or cyclosporine A (CyA) treatment against traumatic brain injury (TBI) in immature rats. Traumatized rats received carnosine [(200 mg/kg/day, in pre-and post-treatment (i.p.)] for 7 consecutive days following TBI. CyA (20 mg/kg, i.p.) was administrated 15 min and 24 h after TBI. The results revealed that TBI caused sever brain injury indicated by increased...
