The plants are very important for living organisms, there would be no life on earth if plants did not exist. Furthermore, when animals or humans consume many plants, they can have negative consequences. Plant toxicity is associated with a multitude of chemical toxins such as alkaloids, glycosides, proteins, and amino acids. There are numerous examples of poisonous species present in different families, one of them Euphorbiaceae. Euphorbiaceae is one of the four largest cosmopolitan families of flowering plants with 313 genera and around 8100, species. Morphological, phytochemical properties and medical uses for 11 wild species of Euphorbiaceae growing in Saudi Arabia were collected in this paper. Two species (Euphorbia fractiflexa and Jatropha glauca) don’t have data for its chemical and medical properties and need a lot of study. For the species growing on the Saudi Arabia, all studied species need further study except for Euphorbia granulata and Ricinus communis.

Parotid tumor is defined as a progressive and abnormal increase in the volume of the parotid due to an excessive multiplication of cells. The diagnosis of tumors is pre, per and postoperative. The treatment is mainly surgical. The objective of this work was to bring out the clinical, para-clinical and therapeutic aspect of parotid tumors. It was Mr D M of Malian nationality, 55 years old, admitted to the stomatology/maxillofacial surgery department of the Nianankoro Fomba hospital in Ségou for treatment of swelling of the right hemiface. The observation of this case relates to a 55-year-old patient who is compatible with the age group of the study conducted by E.S. Diom et al., The average age of the patients was 40 years with extremes of 5 years and 80 years [1]. Parotid tumors are mixed tumors. The latent nature of some of them sometimes makes us see long evolutions, voluminous forms which can evolve into cancerous forms.

Extracts of fresh leaves of Moringa leaf (Moringa oleifera) and Pumpkin (Telferia occidentalis) were administered to broiler chickens in a study that lasted for 8 weeks to evaluate the growth performance, blood serum vitamins and minerals of the birds. A total of 210 day-old broiler chicks were randomly allocated into various pens which consisted of 7 different groups (treatments) with each one having 30 birds. Treatment 1 birds served as the control and were offered commercial synthetic multi-vitamins (vitalyte) in their drinking water. Treatment 2 birds had 50ml moringa leaf extract (MLE) per liter of water while Treatments 3 was 50ml pumpkin leaf extract (PLE) per liter of water. Treatment 4 was 100ml MLE and 5, 100ml PLE. Treatment 6 birds had a mixture or a combination of MLE and PLE (50ml MLE+50ml PLE), while treatment 7 was also a mixture of MLE and PLE (100ml MLE+100ml PLE). Commercial broiler starter and finisher feeds were offered throughout the duration of the experiment. Data were collected on feed intake, weight gain, feed conversion ratio and water intake. On the last day, blood samples were collected for serum vitamins and minerals analysis. The results showed that the extracts significantly (P<0.05) affected all the parameters assessed. Growth parameters per chicken; final live weight gain (3044.65g), daily feed intake (97.06g) and feed conversion ratio (1.84) were best in chickens given 100ml/L MLE while other leaf extracts treated birds compared favorably with the vitalyte chickens. Chickens offered moringa and pumpkin leaves extracts had higher concentrations of the assayed vitamins and minerals; vitamins A, C, D and E; potassium, calcium, magnesium and iron except for sodium. It was therefore concluded that extracts of M. oleifera and pumpkin leaves could serve as organic substitutes to the synthetic commercial multivitamins (vitalyte) in broiler chicken nutrition. Also the residual effects of the use of synthetic vitamins will be reduced.

Agriculture has made significant strides recently, and sustainability build on those successes by using a smart strategy that may maintain greater returns and farm profitability without depleting the resources. Furthermore, nano-materials enhance the efficiency of farm production to enable site targeted regulated distribution of minerals, assuring the least amount of agri-input usage while enhancing crop output. Particularly in the agriculture industry, nanoscienceis crucial for agricultural production, food packaging and processing, water purification, nutrition security, and pollution control as well as crop development and plant preservation. NPs display a well-organized antibacterial activity towards bacteria and viruses. Important inorganic NPs with effective pesticide characteristics include silver, aluminum and copper. Chitosan nano-particles, ZnO nano-particles, and silica nano-particles are beneficial for the treatment of virus infection, including the mosaic virus in tobacco, potatoes, and alfalfa. The revitalization of the damaged soil resources may be possible using nano-enabled soil rehabilitation. The toxicity copper in soil is typically linked to soluble free metal ion species like Cu2+, that are easily accessible and extremely hazardous, in traditional forms of higher soil.
