This study will investigate the efficacy of G-CSF mobilized mononuclear cell injection of patients with PAD who presented with intermittent claudication. Forty PAD patients who presented with intermittent claudication will be randomized into 2 groups. The control group will be treated by medication and walking exercise 3 times/ week. The experiment group will be injected G-CSF mobilized mononuclear cell ,medication and walking exercise 3 times/ week. Ankle brachial index(ABI), Toe brachial index (TBI) and transcutaneous oxygen measurement will be evaluated at the day of randomization, 1 , 3, 6 and 12 months

| PB-MNC therapy | Procedure | The patients will receive subcutaneous injection of Granulocyte colony stimulating factor (G-CSF) for 3 day. The mononuclear cell will be collected by blood cell separator. The 120 cc of cell solution will be injected into calf or thigh of ischemic limb (1cc per site) with needle no. 25 gauge. Patients will receive ASA 81 mg once daily and walking exercise 3 times/ week |
| Measure | Description | Time Frame |
|---|---|---|
| Pain free walking distance | the maximum distance which patient could walk without pain | 3 month |
| Measure | Description | Time Frame |
|---|---|---|
| Ankle brachial index (ABI) | Ankle brachial indexThe Ankle Brachial Index (ABI) is the systolic pressure at the ankle, divided by the systolic pressure at the arm. It has been shown to be a specific and sensitive metric for the diagnosis of Peripheral Arterial Disease (PAD) | 1,3,6,12 month |
