Aziz, "The role of PDE5 inhibitors in heme oxygenase-cGMP relationship in rat cavernous tissues.", The journal of sexual medicine, vol. 5, issue 7, pp. 1636-45, 2008 Jul. Abstract

INTRODUCTION: Heme oxygenase (HO) enzyme catalyzes oxidative degradation of heme to biliverdin and carbon monoxide (CO). CO shares many properties with nitric oxide (NO) including the activation of soluble guanyl cyclase.

AIM: To assess cavernous tissue HO activity and cyclic guanosine monophosphate (cGMP) levels in response to oral phosphodiesterase type 5 (PDE5) inhibitors.

METHODS: Seven hundred twenty male Sprague-Dawley rats, divided into six groups, were investigated. Group 1, controls; group 2 received sildenafil citrate orally; group 3 received vardenafil hydrochloride; and group 4 received tadalafil. Group 5 was subdivided into three equal subgroups, received the same dose of each drug added to the HO inhibitor, Zn protoporphyrin. Group 6 was subdivided into three equal subgroups, received the same dose of each drug added to the NO inhibitor, L-nitroarginine methylester. Eight rats from each group/subgroup were sacrificed at 0.5, 1, 2, 3, 4, 6, 18, 24, and 36 hours, respectively.

MAIN OUTCOME MEASURES: HO enzyme activity assay and cGMP tissue levels in dissected rat cavernous tissues.

RESULTS: Both cavernous tissue HO enzyme activity and cGMP levels were increased significantly in sildenafil-, vardenafil-, and tadalafil-treated rats compared with the controls, with significant decreases after either HO or NO inhibition. Cavernous tissue HO enzyme activity and cGMP showed a positive significant correlation (r = 0.854, P < 0.001).

CONCLUSION: The effects of PDE5 inhibitors in cavernous tissue are partly mediated through HO enzyme activity.

The non-isothermal melt crystallization kinetics of a series of copoly(ester-urethane)s, PUs, based on poly(3-hydroxybutyrate), PHB, and poly(butylene adipate), PBA, of different PHB content 20, 40, and 60 wt% were studied using DSC at different cooling rates. Various macrokinetic models, namely, Avrami, Tobin, Ozawa, and Mo models were applied to describe the crystallization process of PHB in the PU matrices. Avrami, Tobin, and Mo models could successfully describe the non-isothermal crystallization behavior of PHB segments in all samples, while Ozawa model provides a fair description of the non-isothermal crystallization process of PUs containing only 20 and 40 wt% PHB. The Avrami exponent was found to range from 3.6 to 4.0, while the Tobin exponent was found to range from 2.3 to 3.0. The spherulites shape and size were analyzed using polarized optical microscopy (POM). The results of kinetic parameters showed that the crystallization rate of PHB segments in the investigated PUs was increased with increasing the PHB content. The isoconversional method of Friedman was used to determine the effective activation energy of crystallization of the PUs and the Lauritzen-Hoffman parameters (Kg and U*) were calculated by applying the Vyazovkin method. © 2014 Elsevier B.V.

Liver diseases are most commonly occurring nowadays, that’s why we are in argent need to develop new strategies in treatment. to evaluate the role of MSCs in regenerating liver cells and to clarify the anti-inflammatory role of HO-1 either alone or as a combined therapy with MSCs. 72 rats were divided into seven groups (n=10 rats/group) as follows, group1: control rats, group 2: CCL4, group 3: CCL4 that received MSCs group 4: CCL4 that received HO-1 inhibitor, group 5: CCL4 that received HO-1 inducer, group 6: CCL4 that received combined MSCs and HO-1 inhibitor , and group 7: CCL4 that received combined MSCs and HO-1 inducer. All groups were evaluated histopathologically with assessment of liver functions. The combined MSCs and HO-1 inducer group showed the highest significant results in ALT (p-value ˂0.05), albumin (p-value ˂0.05), HO-1 activity (p-value ˂0.0001), and genes expression compared to other groups. This is due to the cumulative anti-inflammatory role of both MSCs and HO-1 together with the ability of MSCs to increase the HO-1 expression with further reduction in inflammation and fibrosis. MSCs and HO-1 inducer provide promising tool in treatment of liver disease.
Key words: MSCs; liver fibrosis; HO-1 inducer; HO-1 inhibitor.
