To study the qualitative changes in testis tissue after carbon tetrachloride (CCl4) administration and to determine whether citric acid (CA) has a protective effect against testis damage induced by CCl4. This study compared two types of CA by measuring the histoarchitecture of the testis and serum levels of progesterone, estrogen and testosterone on mice. One of the most produced organic acid is citric acid. In this study, CA produced by microbial fermentation using Aspergillus Niger 5mg/kg and derived from citrus limon 400mg/kg (lemon). Mice were treated with daily intraperitoneal (i.p.) injection for seven successive days after randomly separated into six groups: (1) control, (2) CCl4 (0.02%), (3) limon citric acid (400 mg/kg), (4) CCl4 (0.02%) plus limon CA (400 mg/kg), (5) Aspergillus Niger citric acid (5 mg/kg), and (6) CCl4 (0.02%) plus Aspergillus Niger CA (5mg/kg). Mice were sacrificed, then the testes were histopathological examined under light microscopy, serum levels of progesterone, estrogen and testosterone tested. Histopathological results indicated that CCl4 severely damage to mouse testis tissues, however, the protective effects on testes was observed when CCl4 combined with CA. Hormone estimation results showed that the treatment of CCl4 exhibited reduction in testosterone level of serum as compared to the control group of mice, in contrast exhibited high in the level of estrogen and progesterone in CCl4 treated group in correlation to that of the standard control group. Sex hormone serum levels were improved by lemon citric acid (CA) and Aspergillus Niger citric acid but did not reach the mean control level
There have been many negative phenomena in Iraqi society, especially after the political crises over the last years, such as the spread of violence, the deterioration of the economic situation, the spread of unemployment and poverty, and the disintegration of social ties, divorce, and the entry of the scourge of drugs.

Esophagus parts showed that composed of four layer ;the mucosa, sub mucosa, muscular and adventitia or serosa, the mucosal layer was arranged in folds which was longer in the c

(Tropaeolumceae) cultivated in different gardens, the roots, stems, leaves, flowers and fruit were studied in detail, also the pollen grains were studied, and there are photographs for all that parts were putted. A specimens of that taxa were studied in some Iraqi herbaria. The study found that there are many characters were used in differentiation of two species under study.
Every body has a size and mass that distinguishes it from others and makes it different from others. Some of these bodies are huge and large in size, and some are small and light in weight. Among these masses and bodies are some that are dealt with by their size and weight, each according to its quantity, weight, and cheapness. This is why they created quantities by which these weights and quantities could be estimated, so they used measures and weights for that. Objectives: The research aims to know some measures and weights, such as the wife’s maintenance, the amount of zakat, etc.I found it to be a widely spread topic, and widely used in the folds of jurisprudence. During my reading of jurisprudence books, I found jurists using many qu
