Microbiological and Pharmacological Evaluation of the Micropropagated Rubus liebmannii Medicinal Plant

Figure 1

Photomicrographs of liver, kidney, spleen, and intestine from male Sprague-Dawley rats in subacute toxicity of the extract from aerial parts of Rubus liebmannii. Cross-sections were stained with hematoxylin and eosin at ×400 (for liver and kidney) and at ×100 (for spleen and intestine). Observations were conducted at different amplified levels. The liver cross-section shows the hepatic artery (HA), bile duct (BD), central vein (CV), sinusoids (S), and hepatocytes (H), all clearly conserved. Cross-section of kidney shows, on magnification, renal corpuscles (RC), tubules (T), and Bowman’s space (BS), all sealed. Spleen cross-section shows red pulp (RP) and white pulp (WP) containing central arteries (CAs), all well defined. Cross-section of intestine shows Peyer patches (PPs) and intestinal mucosa (IM), with all of these structures also found to be totally conserved.
