An immunosuppressive agent used in organtransplant patients is
1)Streptokinase
2) Statins
3) Cyclosporin-A
4) Lipases

Options

A. Streptokinase
B. Statins
C. Cyclosporin-A
D. Lipases

Answer

To determine the immunosuppressive agent used in organ transplant patients, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an immunosuppressive agent that is specifically used in organ transplant patients. Immunosuppressive agents are medications that lower the body's immune response to prevent rejection of transplanted organs.

2. **Analyzing Option 1: Streptokinase**:
- Streptokinase is an enzyme that dissolves blood clots.
- Its primary function is to act as a thrombolytic agent, which means it helps in breaking down clots in blood vessels.
- **Conclusion**: Streptokinase does not have immunosuppressive properties and is not used in organ transplantation.

3. **Analyzing Option 2: Statins**:
- Statins are drugs that lower blood cholesterol levels.
- They are primarily used to manage cholesterol and reduce the risk of cardiovascular diseases.
- **Conclusion**: Statins do not act as immunosuppressive agents and are not relevant in the context of organ transplantation.

4. **Analyzing Option 3: Cyclosporin-A**:
- Cyclosporin-A is a chemical compound derived from the fungus Trichoderma polysporum.
- It is specifically known for its ability to suppress the immune response, making it effective in preventing organ rejection after transplants.
- **Conclusion**: Cyclosporin-A is indeed an immunosuppressive agent and is widely used in organ transplant patients.

5. **Analyzing Option 4: Lipases**:
- Lipases are enzymes that help in the digestion of fats.
- They are not involved in immune response modulation.
- **Conclusion**: Lipases do not have immunosuppressive properties and are not used in organ transplantation.

### Final Answer:
The correct answer is **3) Cyclosporin-A**.
