Alloxan treatment destroys

Options

A. STH cells
B. Cells of Leydig
C. Beta cells of Islets of Langerhans
D. Alpha cells of Islets of Langerhans

Answer

**Step-by-Step Solution:**

1. **Understanding Alloxan**: Alloxan is a compound that is known to be toxic to certain cells in the pancreas. It is often used in laboratory settings to induce diabetes in experimental animals.

2. **Identifying Target Cells**: The pancreas contains clusters of cells known as the islets of Langerhans, which are responsible for producing hormones such as insulin. Within these islets, there are different types of cells:
- **Alpha cells**: Produce glucagon.
- **Beta cells**: Produce insulin.
- **Delta cells**: Produce somatostatin.

3. **Effect of Alloxan**: Alloxan specifically targets and destroys the beta cells of the islets of Langerhans. These cells are crucial for insulin production, which regulates blood glucose levels.

4. **Consequences of Beta Cell Destruction**: When beta cells are destroyed, insulin production decreases significantly, leading to elevated blood glucose levels, which is a characteristic of diabetes.

5. **Conclusion**: Therefore, the correct answer to the question "Alloxan treatment destroys" is the beta cells of the islet of Langerhans.

**Final Answer**: Beta cells of islet of Langerhans.
