Spiropyrim.dines vanquish a significant situation in the field of heterocyclic chem.stry, they are broadly utilized as an antibacterial, an inhibitor of m.ltidrug opposition, or an antiplatelet and antithrom.otic drug. Phosphate, the principal m.roccan m.neral wealth occupies a vital spot in the econom.c sector and its valuation is a goal continually looked for. Am.ng the conceivable outcom.s of valorization, its utilization in heterogeneous catalysis which thought about an exceptionally encouraging new way. In this context, the focus on the reaction of the synthesis of spiropy-rim.dine, catalyzed by natural phosphate (NP) and by fluoroapatite (Fap), are used alone or doped by cobalt. These phosphate catalysts were characterized by XRD, IR and SEm. while the synthesized spiropyrim.dine was identified by IR, GC-m. and Nm.. The obtained yield with fluorapatite doped by cobalt (Co/Fap), at room.tem.erature in ethanol is very high and shows a high im.act perform.nce induced by a synergistic effect com.ared to that of NP alone.

Let C be a sem.dualizing m.dule for a com.utative ring R. It is shown that the ：IC-injective dim.nsion has the ability to detect the regularity of R as well as the Pc-projective dim.nsion. It is proved that if D is dualizing for a Noetherian ring R such that idR（D） = n 〈 ∞, then ：ID-idR（F） ≤ n for every flat R-m.dule F. This extends the result due to Enochs and Jenda. Finally, over a Noetherian ring R, it is shown that if m.is a pure subm.dule of an R-m.dule N, then/TC-idR（m. ≤ IC-idR（N）. This generalizes the result of Enochs and Holm.

AIm.To evaluate the effect of chronic m.ld stress(Cm.) on the em.rgence of gastric ulcers and possible m.dulation by octreotide,a synthetic som.tostatin analogue. m.THODS:Adult m.le Wistar rats were subjected to nine different unpredictable random.stress procedures for 21 d,a m.ltifactorial interactional anim.l m.del for *** was adm.nistered daily for 21 d at two dose levels(50 and 90μg/kg)before exposure to stress ***-and m.croscopical assessm.nts were m.de,in addition to quantification of plasm. corticosterone and gastric m.cosal inflam.atory,oxidative stress, and apoptotic biom.rkers. RESULTS:Exposure to Cm. elevated plasm. corticosterone(28.3±0.6μg/dL,P=0.002),an event that was accom.anied by gastric lesions(6.4±0.16 m.,P=0.01) and confirm.d ***,the insult elevated gastric m.cosal lipid peroxides(13±0.5 nm.l/g tissue,P=0.001),tum.r necrosis factor-α(3008.6±78.18 pg/g tissue,Pm. protein,P=0.002).Conversely,Cm. m.tigated interleukin-10(627.9±12.82 pg/g tissue,P= 0.001).Furtherm.re,in anim.ls exposed to Cm.,octreotide restored plasm. corticosterone(61%and 71%from.Cm.,P=0.002)at both dose *** beneficial effects were associated with a rem.rkable suppression of gastric lesions(38%and 9%from.Cm.,P=0.01)and reversal of derangem.nts in gastric m.cosa. CONCLUSION:The current investigation provides evidence that exposure to Cm. induces gastric ulceration, which was alleviated by adm.nistration of octreotide possibly possessing antioxidant,anti-inflam.atory,and anti-apoptotic actions.
